چکیده
We characterise the class of all claw-free t-perfect graphs by forbidden t-minors. Moreover, we show that claw-free t-perfect graphs are 3-colourable. Such a colouring can be obtained in polynomial time.

On claw-free t-perfect graphs
A graph is called t-perfect, if its stable set polytope is defined by nonnegativity, edge and odd-cycle inequalities. We characterise the class of all claw-free t-perfect graphs by forbidden t-minors. Moreover, we show that claw-free t-perfect graphs are 3-colourable. Such a colouring can be obtained in polynomial time.
متن کاملThe Structure of Claw-Free Perfect Graphs
In 1988, Chvátal and Sbihi [4] proved a decomposition theorem for claw-free perfect graphs. They showed that claw-free perfect graphs either have a clique-cutset or come from two basic classes of graphs called elementary and peculiar graphs. In 1999, Maffray and Reed [6] successfully described how elementary graphs can be built using line-graphs of bipartite graphs using local augmentation. How...
متن کاملClaw-Free t-Perfect Graphs Can Be Recognised in Polynomial Time
A graph is called t-perfect if its stable set polytope is defined by nonnegativity, edge and odd-cycle inequalities. We show that it can be decided in polynomial time whether a given claw-free graph is t-perfect.
متن کاملt-Perfection Is Always Strong for Claw-Free Graphs
A connected graph G is called t-perfect if its stable set polytope is determined by the non-negativity, edge and odd-cycle inequalities. Moreover, G is called strongly t-perfect if this system is totally dual integral. It is an open problem whether t-perfection is equivalent to strong t-perfection. We prove the equivalence for the class of claw-free graphs.
متن کاملInteger round-up property for the chromatic number of some h-perfect graphs
A graph is h-perfect if its stable set polytope can be completely described by nonnegativity, clique and odd-hole constraints. It is t-perfect if it furthermore has no clique of size 4. For every graph G and every c ∈ Z (G) + , the weighted chromatic number of (G, c) is the minimum cardinality of a multi-set F of stable sets of G such that every v ∈ V (G) belongs to at least cv members of F . W...
