A new characterization of trivially perfect graphs

چکیده
A graph G is trivially perfect if for every induced subgraph the cardinality of the largest set of pairwise nonadjacent vertices (the stability number) α(G) equals the number of (maximal) cliques m(G). We characterize the trivially perfect graphs in terms of vertex-coloring and we extend some definitions to infinite graphs.

Linear-time certifying algorithms for recognizing trivially perfect graphs
We give the first linear-time certifying algorithms to recognize trivially perfect graphs, with sublinear certificates for negative output. In case of membership in the class of trivially perfect graphs, our algorithms provide as certificate a structure for the input graph that characterizes the class, and in case of non-membership they provide as certificate a forbidden induced subgraph of the...
متن کاملEnumerative aspects of certain subclasses of perfect graphs
We investigate the enumerative aspects of various classes of perfect graphs like cographs, split graphs, trivially perfect graphs and threshold graphs. For subclasses of permutation graphs like cographs and threshold graphs we also determine the number of permutations of f1; 2; : : : ; ng such that the permutation graph G] belongs to that class. We establish an interesting bijec-tion between pe...
متن کاملComputing square roots of trivially perfect and threshold graphs
A graph H is a square root of a graph G if two vertices are adjacent in G if and only if they are at distance one or two in H . Computing a square root of a given graph is NP-hard, even when the input graph is restricted to be chordal. In this paper, we show that computing a square root can be done in linear time for a well-known subclass of chordal graphs, the class of trivially perfect graphs...
متن کاملProbe threshold and probe trivially perfect graphs
7 An undirected graph G = (V,E) is a probe C graph if its vertex set can be partitioned 8 into two sets, N (non-probes) and P (probes) where N is independent and there 9 exists E′ ⊆ N × N such that G′ = (V,E ∪ E′) is a C graph. In this article we 10 investigate probe threshold and probe trivially perfect graphs and characterise them 11 in terms of certain 2-Sat formulas and in other ways. For t...
متن کاملA generalization of Villarreal's result for unmixed tripartite graphs
In this paper we give a characterization of unmixed tripartite graphs under certain conditions which is a generalization of a result of Villarreal on bipartite graphs. For bipartite graphs two different characterizations were given by Ravindra and Villarreal. We show that these two characterizations imply each other.
