报告题目:Existence of properly colored regular factors in edge colored graphs
摘要:We review conditions for existence of (regular) factors in graphs. Then we will show how to extend them to the colored case. We also present results related to complexity of actually finding such factors. The talk will be based on a joint work with M. Furuya, K. Kimura, K. Ozeki, Ch. Purcell and T. Yashima.
