matrix representation of relations

For example, let us use Eq. Example $\PageIndex{3}$: Relations and Information, This final example gives an insight into how relational data base programs can systematically answer questions pertaining to large masses of information. \PMlinkescapephraserelation Draw two ellipses for the sets P and Q. You may not have learned this yet, but just as $M_R$ tells you what one-step paths in $\{1,2,3\}$ are in $R$, $$M_R^2=\begin{bmatrix}0&1&0\\0&1&0\\0&1&0\end{bmatrix}\begin{bmatrix}0&1&0\\0&1&0\\0&1&0\end{bmatrix}=\begin{bmatrix}0&1&0\\0&1&0\\0&1&0\end{bmatrix}$$, counts the number of $2$-step paths between elements of $\{1,2,3\}$. (Note: our degree textbooks prefer the term \degree", but I will usually call it \dimension . Definition $\PageIndex{1}$: Adjacency Matrix, Let $A = \{a_1,a_2,\ldots , a_m\}$ and $B= \{b_1,b_2,\ldots , b_n\}$ be finite sets of cardinality $m$ and $n\text{,}$ respectively. &\langle 2,2\rangle\land\langle 2,2\rangle\tag{2}\\ For each graph, give the matrix representation of that relation. A matrix representation of a group is defined as a set of square, nonsingular matrices (matrices with nonvanishing determinants) that satisfy the multiplication table of the group when the matrices are multiplied by the ordinary rules of matrix multiplication. >T_nO Append content without editing the whole page source. Research into the cognitive processing of logographic characters, however, indicates that the main obstacle to kanji acquisition is the opaque relation between . Now they are all different than before since they've been replaced by each other, but they still satisfy the original . Given the 2-adic relations PXY and QYZ, the relational composition of P and Q, in that order, is written as PQ, or more simply as PQ, and obtained as follows: To compute PQ, in general, where P and Q are 2-adic relations, simply multiply out the two sums in the ordinary distributive algebraic way, but subject to the following rule for finding the product of two elementary relations of shapes a:b and c:d. (a:b)(c:d)=(a:d)ifb=c(a:b)(c:d)=0otherwise. Find out what you can do. If there is an edge between V x to V y then the value of A [V x ] [V y ]=1 and A [V y ] [V x ]=1, otherwise the value will be zero. Comput the eigenvalues $\lambda_1\le\cdots\le\lambda_n$ of $K$. Matrices $R$ (on the left) and $S$ (on the right) define the relations $r$ and $s$ where $a r b$ if software $a$ can be run with operating system $b\text{,}$ and $b s c$ if operating system $b$ can run on computer $c\text{. the meet of matrix M1 and M2 is M1 ^ M2 which is represented as R1 R2 in terms of relation. }$ So that, since the pair $(2, 5) \in r\text{,}$ the entry of $R$ corresponding to the row labeled 2 and the column labeled 5 in the matrix is a 1. English; . is the adjacency matrix of B(d,n), then An = J, where J is an n-square matrix all of whose entries are 1. Antisymmetric relation is related to sets, functions, and other relations. Because certain things I can't figure out how to type; for instance, the "and" symbol. Acceleration without force in rotational motion? By way of disentangling this formula, one may notice that the form kGikHkj is what is usually called a scalar product. Entropies of the rescaled dynamical matrix known as map entropies describe a . Let r be a relation from A into . For example, consider the set $X = \{1, 2, 3 \}$ and let $R$ be the relation where for $x, y \in X$ we have that $x \: R \: y$ if $x + y$ is divisible by $2$, that is $(x + y) \equiv 0 \pmod 2$. A relation from A to B is a subset of A x B. In this set of ordered pairs of x and y are used to represent relation. We can check transitivity in several ways. }\), $\begin{array}{cc} & \begin{array}{ccc} 4 & 5 & 6 \\ \end{array} \\ \begin{array}{c} 1 \\ 2 \\ 3 \\ 4 \\ \end{array} & \left( \begin{array}{ccc} 0 & 0 & 0 \\ 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \\ \end{array} \right) \\ \end{array}$ and $\begin{array}{cc} & \begin{array}{ccc} 6 & 7 & 8 \\ \end{array} \\ \begin{array}{c} 4 \\ 5 \\ 6 \\ \end{array} & \left( \begin{array}{ccc} 0 & 0 & 0 \\ 1 & 0 & 0 \\ 0 & 1 & 0 \\ \end{array} \right) \\ \end{array}$, $\displaystyle r_1r_2 =\{(3,6),(4,7)\}$, $\displaystyle \begin{array}{cc} & \begin{array}{ccc} 6 & 7 & 8 \\ \end{array} \\ \begin{array}{c} 1 \\ 2 \\ 3 \\ 4 \\ \end{array} & \left( \begin{array}{ccc} 0 & 0 & 0 \\ 0 & 0 & 0 \\ 1 & 0 & 0 \\ 0 & 1 & 0 \\ \end{array} \right) \\ \end{array}$, Determine the adjacency matrix of each relation given via the digraphs in, Using the matrices found in part (a) above, find $r^2$ of each relation in. A new representation called polynomial matrix is introduced. WdYF}21>Yi, =k|0EA=tIzw+/M>9CGr-VO=MkCfw;-{9 ;,3~|prBtm]. See pages that link to and include this page. There are many ways to specify and represent binary relations. For instance, let. For example, the strict subset relation is asymmetric and neither of the sets {3,4} and {5,6} is a strict subset of the other. Fortran uses "Column Major", in which all the elements for a given column are stored contiguously in memory. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. We write a R b to mean ( a, b) R and a R b to mean ( a, b) R. When ( a, b) R, we say that " a is related to b by R ". }\) Then using Boolean arithmetic, $R S =\left( \begin{array}{cccc} 0 & 0 & 1 & 1 \\ 0 & 1 & 1 & 1 \\ 0 & 0 & 1 & 1 \\ 0 & 0 & 0 & 1 \\ \end{array} \right)$ and $S R=\left( \begin{array}{cccc} 1 & 1 & 1 & 1 \\ 0 & 1 & 1 & 1 \\ 0 & 0 & 1 & 0 \\ 0 & 0 & 0 & 0 \\ \end{array} \right)\text{. The matrix representation of the equality relation on a finite set is the identity matrix I, that is, the matrix whose entries on the diagonal are all 1, while the others are all 0.More generally, if relation R satisfies I R, then R is a reflexive relation.. }$ Since $r$ is a relation from $A$ into the same set $A$ (the $B$ of the definition), we have $a_1= 2\text{,}$ $a_2=5\text{,}$ and $a_3=6\text{,}$ while $b_1= 2\text{,}$ $b_2=5\text{,}$ and \(b_3=6\text{. A relation follows meet property i.r. A MATRIX REPRESENTATION EXAMPLE Example 1. This confused me for a while so I'll try to break it down in a way that makes sense to me and probably isn't super rigorous. If so, transitivity will require that $\langle 1,3\rangle$ be in $R$ as well. Wikidot.com Terms of Service - what you can, what you should not etc. How to increase the number of CPUs in my computer? For a vectorial Boolean function with the same number of inputs and outputs, an . Yes (for each value of S 2 separately): i) construct S = ( S X i S Y) and get that they act as raising/lowering operators on S Z (by noticing that these are eigenoperatos of S Z) ii) construct S 2 = S X 2 + S Y 2 + S Z 2 and see that it commutes with all of these operators, and deduce that it can be diagonalized . Relation as Matrices:A relation R is defined as from set A to set B, then the matrix representation of relation is MR= [mij] where. For example, to see whether $\langle 1,3\rangle$ is needed in order for $R$ to be transitive, see whether there is a stepping-stone from $1$ to $3$: is there an $a$ such that $\langle 1,a\rangle$ and $\langle a,3\rangle$ are both in $R$? A relation follows meet property i.r. Legal. /Filter /FlateDecode Relation as an Arrow Diagram: If P and Q are finite sets and R is a relation from P to Q. In other words, all elements are equal to 1 on the main diagonal. and the relation on (ie. ) How exactly do I come by the result for each position of the matrix? i.e. A relation R is symmetric if the transpose of relation matrix is equal to its original relation matrix. Directed Graph. Example 3: Relation R fun on A = {1,2,3,4} defined as: If your matrix $A$ describes a reflexive and symmetric relation (which is easy to check), then here is an algebraic necessary condition for transitivity (note: this would make it an equivalence relation). Irreflexive Relation. Discussed below is a perusal of such principles and case laws . Click here to edit contents of this page. r 2. Stripping down to the bare essentials, one obtains the following matrices of coefficients for the relations G and H. G=[0000000000000000000000011100000000000000000000000], H=[0000000000000000010000001000000100000000000000000]. Asymmetric Relation Example.

Learn more about Stack Overflow the company, and our products. Then r can be represented by the m n matrix R defined by. So what *is* the Latin word for chocolate? How does a transitive extension differ from a transitive closure? A matrix diagram is defined as a new management planning tool used for analyzing and displaying the relationship between data sets. Here's a simple example of a linear map: x x. 90 Representing Relations Using MatricesRepresenting Relations Using Matrices This gives us the following rule:This gives us the following rule: MMBB AA = M= MAA M MBB In other words, the matrix representing theIn other words, the matrix representing the compositecomposite of relations A and B is theof relations A and B is the . Relation as a Table: If P and Q are finite sets and R is a relation from P to Q. Can you show that this cannot happen? Notify administrators if there is objectionable content in this page. These are given as follows: Set Builder Form: It is a mathematical notation where the rule that associates the two sets X and Y is clearly specified. Therefore, a binary relation R is just a set of ordered pairs. composition The basic idea is this: Call the matrix elements $a_{ij}\in\{0,1\}$. Prove that $R \leq S \Rightarrow R^2\leq S^2$ , but the converse is not true. 9Q/5LR3BJ yh?/*]q/v}s~G|yWQWd\RG ]8&jNu:BPk#TTT0N\W]U7D wr&`DDH' ;:UdH'Iu3u&YU k9QD[1I]zFy nw`P'jGP$]ED]F Y-NUE]L+c"nz_5'>nzwzp\&NI~QQfqy'EEDl/]E]%uX$u;$;b#IKnyWOF?}GNsh3B&1!nz{"_T>.}`v{kR2~"nzotwdw},NEE3}E$n~tZYuW>O; B>KUEb>3i-nj\K}&&^*jgo+R&V*o+SNMR=EI"p\uWp/mTb8ON7Iz0ie7AFUQ&V*bcI6& F F>VHKUE=v2B&V*!mf7AFUQ7.m&6"dc[C@F wEx|yzi'']! The relation is transitive if and only if the squared matrix has no nonzero entry where the original had a zero. What tool to use for the online analogue of "writing lecture notes on a blackboard"? So we make a matrix that tells us whether an ordered pair is in the set, let's say the elements are $\{a,b,c\}$ then we'll use a $1$ to mark a pair that is in the set and a $0$ for everything else. On this page, we we will learn enough about graphs to understand how to represent social network data. Using we can construct a matrix representation of as We will now prove the second statement in Theorem 1. This can be seen by But the important thing for transitivity is that wherever $M_R^2$ shows at least one $2$-step path, $M_R$ shows that there is already a one-step path, and $R$ is therefore transitive. How to determine whether a given relation on a finite set is transitive? #matrixrepresentation #relation #properties #discretemathematics For more queries :Follow on Instagram :Instagram : https://www.instagram.com/sandeepkumargou. First of all, while we still have the data of a very simple concrete case in mind, let us reflect on what we did in our last Example in order to find the composition GH of the 2-adic relations G and H. G=4:3+4:4+4:5XY=XXH=3:4+4:4+5:4YZ=XX. For each graph, give the matrix representation of that relation. Previously, we have already discussed Relations and their basic types.

You can multiply by a scalar before or after applying the function and get the same result. This paper aims at giving a unified overview on the various representations of vectorial Boolean functions, namely the Walsh matrix, the correlation matrix and the adjacency matrix. Write down the elements of P and elements of Q column-wise in three ellipses. Determine the adjacency matrices of. As India P&O Head, provide effective co-ordination in a matrixed setting to deliver on shared goals affecting the country as a whole, while providing leadership to the local talent acquisition team, and balancing the effective sharing of the people partnering function across units. (a,a) & (a,b) & (a,c) \\ In the original problem you have the matrix, $$M_R=\begin{bmatrix}1&0&1\\0&1&0\\1&0&1\end{bmatrix}\;,$$, $$M_R^2=\begin{bmatrix}1&0&1\\0&1&0\\1&0&1\end{bmatrix}\begin{bmatrix}1&0&1\\0&1&0\\1&0&1\end{bmatrix}=\begin{bmatrix}2&0&2\\0&1&0\\2&0&2\end{bmatrix}\;.$$. Example: { (1, 1), (2, 4), (3, 9), (4, 16), (5, 25)} This represent square of a number which means if x=1 then y . Transitivity on a set of ordered pairs (the matrix you have there) says that if $(a,b)$ is in the set and $(b,c)$ is in the set then $(a,c)$ has to be. A-143, 9th Floor, Sovereign Corporate Tower, We use cookies to ensure you have the best browsing experience on our website. Fortran and C use different schemes for their native arrays. \end{bmatrix} 2. These are the logical matrix representations of the 2-adic relations G and H. If the 2-adic relations G and H are viewed as logical sums, then their relational composition G H can be regarded as a product of sums, a fact that can be indicated as follows: Variation: matrix diagram. Trouble with understanding transitive, symmetric and antisymmetric properties. I am sorry if this problem seems trivial, but I could use some help. KVy\mGZRl\t-NYx}e>EH J Abstract In this paper, the Tsallis entropy based novel uncertainty relations on vector signals and matrix signals in terms of sparse representation are deduced for the first time. Let $A = \{a, b, c, d\}\text{. The arrow diagram of relation R is shown in fig: 4. Change the name (also URL address, possibly the category) of the page. Let M R and M S denote respectively the matrix representations of the relations R and S. Then. ## Code solution here. \PMlinkescapephraseorder 'a' and 'b' being assumed as different valued components of a set, an antisymmetric relation is a relation where whenever (a, b) is present in a relation then definitely (b, a) is not present unless 'a' is equal to 'b'.Antisymmetric relation is used to display the relation among the components of a set . If exactly the first $m$ eigenvalues are zero, then there are $m$ equivalence classes $C_1,,C_m$. General Wikidot.com documentation and help section. An Adjacency Matrix A [V] [V] is a 2D array of size V V where V is the number of vertices in a undirected graph. To fill in the matrix, \(R_{ij}$ is 1 if and only if $\left(a_i,b_j\right) \in r\text{. Let and Let be the relation from into defined by and let be the relation from into defined by. Suppose V= Rn,W =Rm V = R n, W = R m, and LA: V W L A: V W is given by. 2 6 6 4 1 1 1 1 3 7 7 5 Symmetric in a Zero-One Matrix Let R be a binary relation on a set and let M be its zero-one matrix. I've tried to a google search, but I couldn't find a single thing on it. <> \(\begin{array}{cc} & \begin{array}{cccc} 1 & 2 & 3 & 4 \\ \end{array} \\ \begin{array}{c} 1 \\ 2 \\ 3 \\ 4 \\ \end{array} & \left( \begin{array}{cccc} 0 & 1 & 0 & 0 \\ 1 & 0 & 1 & 0 \\ 0 & 1 & 0 & 1 \\ 0 & 0 & 1 & 0 \\ \end{array} \right) \\ \end{array}$ and $\begin{array}{cc} & \begin{array}{cccc} 1 & 2 & 3 & 4 \\ \end{array} \\ \begin{array}{c} 1 \\ 2 \\ 3 \\ 4 \\ \end{array} & \left( \begin{array}{cccc} 1 & 0 & 1 & 0 \\ 0 & 1 & 0 & 1 \\ 1 & 0 & 1 & 0 \\ 0 & 1 & 0 & 1 \\ \end{array} \right) \\ \end{array}$, $P Q= \begin{array}{cc} & \begin{array}{cccc} 1 & 2 & 3 & 4 \\ \end{array} \\ \begin{array}{c} 1 \\ 2 \\ 3 \\ 4 \\ \end{array} & \left( \begin{array}{cccc} 0 & 1 & 0 & 0 \\ 1 & 0 & 1 & 0 \\ 0 & 1 & 0 & 1 \\ 0 & 0 & 1 & 0 \\ \end{array} \right) \\ \end{array}$ $P^2 =\text{ } \begin{array}{cc} & \begin{array}{cccc} 1 & 2 & 3 & 4 \\ \end{array} \\ \begin{array}{c} 1 \\ 2 \\ 3 \\ 4 \\ \end{array} & \left( \begin{array}{cccc} 0 & 1 & 0 & 0 \\ 1 & 0 & 1 & 0 \\ 0 & 1 & 0 & 1 \\ 0 & 0 & 1 & 0 \\ \end{array} \right) \\ \end{array}$$=Q^2$, Prove that if $r$ is a transitive relation on a set $A\text{,}$ then \(r^2 \subseteq r\text{. Matrix Representation. It can only fail to be transitive if there are integers $a, b, c$ such that (a,b) and (b,c) are ordered pairs for the relation, but (a,c) is not. \\ However, matrix representations of all of the transformations as well as expectation values using the den-sity matrix formalism greatly enhance the simplicity as well as the possible measurement outcomes. One of the best ways to reason out what GH should be is to ask oneself what its coefficient (GH)ij should be for each of the elementary relations i:j in turn. Is this relation considered antisymmetric and transitive? The tabular form of relation as shown in fig: JavaTpoint offers too many high quality services. Relations are generalizations of functions. There are five main representations of relations. CS 441 Discrete mathematics for CS M. Hauskrecht Anti-symmetric relation Definition (anti-symmetric relation): A relation on a set A is called anti-symmetric if [(a,b) R and (b,a) R] a = b where a, b A. What does a search warrant actually look like? Append content without editing the whole page source. Dealing with hard questions during a software developer interview, Clash between mismath's \C and babel with russian. Family relations (like "brother" or "sister-brother" relations), the relation "is the same age as", the relation "lives in the same city as", etc. Such studies rely on the so-called recurrence matrix, which is an orbit-specific binary representation of a proximity relation on the phase space.. | Recurrence, Criticism and Weights and . Recall from the Hasse Diagrams page that if $X$ is a finite set and $R$ is a relation on $X$ then we can construct a Hasse . \end{align*}$$. Choose some $i\in\{1,,n\}$. A relation R is symmetricif and only if mij = mji for all i,j. The best answers are voted up and rise to the top, Not the answer you're looking for? In the Jamio{\\l}kowski-Choi representation, the given quantum channel is described by the so-called dynamical matrix. Create a matrix A of size NxN and initialise it with zero. All that remains in order to obtain a computational formula for the relational composite GH of the 2-adic relations G and H is to collect the coefficients (GH)ij over the appropriate basis of elementary relations i:j, as i and j range through X. GH=ij(GH)ij(i:j)=ij(kGikHkj)(i:j). Some of which are as follows: Listing Tuples (Roster Method) Set Builder Notation; Relation as a Matrix TOPICS. In this section we will discuss the representation of relations by matrices. Taking the scalar product, in a logical way, of the fourth row of G with the fourth column of H produces the sole non-zero entry for the matrix of GH. It is shown that those different representations are similar. Some Examples: We will, in Section 1.11 this book, introduce an important application of the adjacency matrix of a graph, specially Theorem 1.11, in matrix theory. \PMlinkescapephraseComposition 2 0 obj }\) Then $r$ can be represented by the $m\times n$ matrix $R$ defined by, \begin{equation*} R_{ij}= \left\{ \begin{array}{cc} 1 & \textrm{ if } a_i r b_j \\ 0 & \textrm{ otherwise} \\ \end{array}\right. Then place a cross (X) in the boxes which represent relations of elements on set P to set Q. The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. I am Leading the transition of our bidding models to non-linear/deep learning based models running in real time and at scale. We have discussed two of the many possible ways of representing a relation, namely as a digraph or as a set of ordered pairs. How many different reflexive, symmetric relations are there on a set with three elements? The representation theory basis elements obey orthogonality results for the two-point correlators which generalise known orthogonality relations to the case with witness fields. ta0Sz1|GP",\ ,aGXNoy~5aXjmsmBkOuhqGo6h2NvZlm)p-6"l"INe-rIoW%[S"LEZ1F",!!"Er XA It is important to realize that a number of conventions must be chosen before such explicit matrix representation can be written down. $$\begin{bmatrix}1&0&1\\0&1&0\\1&0&1\end{bmatrix}$$. }\) If $R_1$ and $R_2$ are the adjacency matrices of $r_1$ and $r_2\text{,}$ respectively, then the product $R_1R_2$ using Boolean arithmetic is the adjacency matrix of the composition $r_1r_2\text{. \end{align} $$. &\langle 3,2\rangle\land\langle 2,2\rangle\tag{3} Relations as Directed graphs: A directed graph consists of nodes or vertices connected by directed edges or arcs.

Let us recall the rule for finding the relational composition of a pair of 2-adic relations. View and manage file attachments for this page. 0 & 0 & 0 \\ Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? compute \(S R$ using regular arithmetic and give an interpretation of what the result describes. The directed graph of relation R = {(a,a),(a,b),(b,b),(b,c),(c,c),(c,b),(c,a)} is represented as : Since, there is loop at every node, it is reflexive but it is neither symmetric nor antisymmetric as there is an edge from a to b but no opposite edge from b to a and also directed edge from b to c in both directions. Click here to toggle editing of individual sections of the page (if possible). As it happens, there is no such $a$, so transitivity of $R$ doesnt require that $\langle 1,3\rangle$ be in $R$. Matrix Representation Hermitian operators replaced by Hermitian matrix representations.In proper basis, is the diagonalized Hermitian matrix and the diagonal matrix elements are the eigenvalues (observables).A suitable transformation takes (arbitrary basis) into (diagonal - eigenvector basis)Diagonalization of matrix gives eigenvalues and . \rightarrow Therefore, we can say, 'A set of ordered pairs is defined as a relation.' This mapping depicts a relation from set A into set B. Given the relation $\{(1,1),(1,2),(2,1),(2,2),(3,3),(4,4)\}$ determine whether it is reflexive, transitive, symmetric, or anti-symmetric. \PMlinkescapephraserelational composition . Trusted ER counsel at all levels of leadership up to and including Board. Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields. The relation is transitive if and only if the squared matrix has no nonzero entry where the original had a zero. If $R$ and $S$ are matrices of equivalence relations and $R \leq S\text{,}$ how are the equivalence classes defined by $R$ related to the equivalence classes defined by \(S\text{? $m_{ij} = \left\{\begin{matrix} 1 & \mathrm{if} \: x_i \: R \: x_j \\ 0 & \mathrm{if} \: x_i \: \not R \: x_j \end{matrix}\right.$, $m_{11}, m_{13}, m_{22}, m_{31}, m_{33} = 1$, Creative Commons Attribution-ShareAlike 3.0 License.

Accomplished senior employee relations subject matter expert, underpinned by extensive UK legal training, up to date employment law knowledge and a deep understanding of full spectrum Human Resources. If youve been introduced to the digraph of a relation, you may find. The quadratic Casimir operator, C2 RaRa, commutes with all the su(N) generators.1 Hence in light of Schur's lemma, C2 is proportional to the d d identity matrix. Relation R can be represented in tabular form. Make the table which contains rows equivalent to an element of P and columns equivalent to the element of Q. When interpreted as the matrices of the action of a set of orthogonal basis vectors for . It only takes a minute to sign up. To find the relational composition GH, one may begin by writing it as a quasi-algebraic product: Multiplying this out in accord with the applicable form of distributive law one obtains the following expansion: GH=(4:3)(3:4)+(4:3)(4:4)+(4:3)(5:4)+(4:4)(3:4)+(4:4)(4:4)+(4:4)(5:4)+(4:5)(3:4)+(4:5)(4:4)+(4:5)(5:4). 2.3.41) Figure 2.3.41 Matrix representation for the rotation operation around an arbitrary angle . Write the matrix representation for this relation. We express a particular ordered pair, (x, y) R, where R is a binary relation, as xRy . r 1. and. Iterate over each given edge of the form (u,v) and assign 1 to A [u] [v]. If $R$ is to be transitive, $(1)$ requires that $\langle 1,2\rangle$ be in $R$, $(2)$ requires that $\langle 2,2\rangle$ be in $R$, and $(3)$ requires that $\langle 3,2\rangle$ be in $R$.
