报告题目:Rainbow cycles in edge-colored graphs
报告简介:Let G be an edge-colored graph of order n. The minimum color degree of G is the largest integer k such that for every vertex v, there are at least k distinct colors on edges incident to v. We say that an edge-colored graph is rainbow if all its edges have different colors. During the past decades, establishing sufficient conditions forcing rainbow cycles has received considerable attention. In this talk, I will introduce minimum color degree conditions for the existence of vertex-disjoint rainbow triangles, and rainbow C_4’s.
