报告题目:Hadwiger’s conjecture for graphs with small independence number
报告简介:In 1943, Hadwiger conjectured that if the chromatic number of a graph G is k, then G has a clique minor of size at least k. Hadwiger’s conjecture remains to be one of the most challenging open problems in graph theory. In this talk, we will review some known results on graphs with small independence number and report our recent work in this direction.
