A biclique of a graph G is a maximal induced complete bipartite subgraph of a graph G, the biclique matrix of G is a {0,1,−1} matrix having one row for each biclique and one column for each vertex of G, and such that a pair of 1, −1 entries in a same row corresponds exactly to adjacent vertices in the corresponding describe a characterization of biclique.

Cliques and Colorings. Given an undirected graph G = (V, E), a clique of the graph is a set of mutually adjacent vertices. A maximum clique is, naturally, a clique whose number of vertices is at least as large as that for any other clique in the graph.

A PARTIAL CHARACTERIZATION OF CLIQUE GRAPHS 5. CONCLUSION The answer to the question of whether a particular graph H is a clique graph depends, apparently, on the clique graph of H and the clique parti- tion of V(H).

The clique partition may also be of use in other parts of graph by: G = G 1 + G 2, give a characterization for clique con vergence of the join of graphs and if G 1, G 2 are Clique-Helly graphs different from K 1 and G = G 1 G 2, then K 2 (G) = G.

Clique graphs of chordal and path graphs are characterized. A special class of graphs named expanded trees is discussed. It consists of a subclass of disk-Helly graphs. It is shown that the clique graph of every chordal (hence path) graph is an expanded tree. In addition, every expanded tree is the clique graph of some path (hence chordal) by: Say that G is a clique graph if there exists a graph H such that G=K(H).

The clique graph recognition problem asks whether a given graph is a clique graph. A sufficient condition was given by Hamelink inand a characterization was proposed by Roberts A characterization of clique graphs book Spencer in We prove that the clique graph recognition problem is by: Given a factor graph F, its completion F is obtained by adding one factor node for each clique in the.

24In usual graph theory, the word clique refers to graph (recall that a graph is defined by a set of nodes and a set of edges which join node pairs), rather than to factor Size: 1MB.

their characterization of clique graphs. Escalante [3], among other results, showed that the clique graph of a Helly graph is Helly, and every Helly graph is the clique graph of some Helly graph.

If n denotes a class of graphs, then let K(17) denote the set of cliques of. Characterization of weighted clique graphs. The characterization of clique graphs is as follows.

Theorem 4 Roberts and Spencer, A graph H is a clique graph if and only if there is a collection F of complete sets of H such that every edge of H is contained in some complete set of F, and F satisfies the Helly by: 2.

Characterization. A graph H is the clique graph K (G) of another graph if and only if there exists a collection C of cliques in H whose union covers all the edges of H, such that C forms a Helly family.

This means that, if S is a subset of C with the property that every two. A characterization of edge-clique graphs of out-erplanar graphs is given; a complete description of edge-clique graphs of threshold graphs is presented and a linear time algorithm for l-coloring the edge-clique graph of a threshold graph is provided.

A survey on the l-coloring problem, when restricted to edge-clique graphs, is reported. clique number within any constant factor is NP-hard (in fact, we can also show the NP-hardness of approximating the clique number within a factor 2loge n, where n is the number of vertices in the graph and e is an arbitrarily small positive constant).

As a class, students create a basic plot diagram of a book they have read. They discuss the use of symbols to represent major events, and assign a positive or negative rating to each plot event they listed. The teacher then turns their ideas into a graphical map.

I sometimes find myself looking for a book to read to my class that will serve as an example of good character or act as a literary pep talk. It might be a book on fairness after an especially tough recess, a book on honesty after someone’s eraser collection goes missing, or maybe a book on perseverance to let a student who is feeling challenged know that it will all work g: clique graphs.1.

INTRODUCTION. We consider simple, finite, undirected graphs. Given a graph G = (V, E), a complete set of G is a subset of V inducing a complete subgraph. A clique is a maximal complete be a family of subsets of a set say that satisfies the Helly property when every subfamily consisting of pairwise intersecting subsets has a non-empty intersection.

In this work, we present a structural result on probe 2-clique graphs that leads to a polynomial-time recognition algorithm for this class, and a forbidden induced subgraph characterization of probe diamond-free graphs implying a forbidden induced subgraph characterization for probe block graphs.
