报告题目:Minimizing the number of edges in partite saturated graphs
报 告 人:陆玫,清华大学,教授
报告摘要:A $K_{k\times\ell}$-saturated $k$-partite graph G is a $k$-partite graph with $n$ vertices in each part such that $G$ is $K_{k\times\ell}$-free but the addition of an edge joining any two non-adjacent vertices from different parts creates a $K_{k\times\ell}$. The minimum number of edges in all $K_{k\times\ell}$-saturated $k$-partite graphs is denoted as $sat(K_{k\times n}$,$K_{k\times\ell})$. In this talk, I will give some results on $sat(K_{k\times n}$,$K_{k\times\ell})$ for $k\ge4$. This work is joint with Yiduo Xu and Zhen He.
