Finding balanced skew partitions in perfect graphs
A graph G is Berge if no induced subgraph of G is an odd cycle of length at least five or the complement of one; and it is known that this is equivalent to being perfect, that is, that the chromatic number of every induced subgraph equals the size of its largest clique. A skew partition in G is a partition (A,B) of V (G) such that G[A] is not connected and G[B] is not connected; and it is balan...
متن کاملClique-Stable Set separation in perfect graphs with no balanced skew-partitions
We prove that perfect graphs with no balanced skew-partitions admits a O(n) Clique-Stable set separator. We then prove that for every graph G in this class, there always exists two subsets of vertices V1, V2 such that |V1|, |V2| ≥ c|V (G)| for some constant c and V1 is either complete or anticomplete to V2. The method uses trigraphs, introduced by Chudnovsky [5], and relies on the good behavior...

متن کاملCombinatorial optimization with 2-joins
A 2-join is an edge cutset that naturally appears in decomposition of several classes of graphs closed under taking induced subgraphs, such as perfect graphs and claw-free graphs. In this paper we construct combinatorial polynomial time algorithms for finding a maximum weighted clique, a maximum weighted stable set and an optimal coloring for a class of perfect graphs decomposable by 2-joins: t...
متن کاملDecomposing Berge graphs and detecting balanced skew partitions
A hole in a graph is an induced cycle on at least four vertices. A graph is Berge if it has no odd hole and if its complement has no odd hole. In 2002, Chudnovsky, Robertson, Seymour and Thomas proved a decomposition theorem for Berge graphs saying that every Berge graph either is in a well understood basic class or has some kind of decomposition. Then, Chudnovsky proved stronger theorems. One ...
