五、摘要

A graphG isk-divisible if for each induced subgraphH ofG, eitherHis a stable set, or V(H)can be partitioned intok sets of which each induces a subgraph with clique number less than ω(G), and is perfectly divisible if for each induced subgraphH ofG,V(H) can be partitioned into two setsA andB such thatH(A)is perfect and ω[H(B)]<ω(H). In this talk, we will present some results on 2-divisibility and perfect divisibility of odd hole free graphs (joint work with Wei Dong and Jialei Song).
