应学院邀请南开大学史永堂教授将与太阳成t官网师生在线上做学术交流并做专题学术报告。

报告题目:Some results on Reconfiguration graphs

报告摘要:For any positive integer $k$, the reconfiguration graph for all $k$-colorings of a graph $G$, denoted by $\mathcal{R}_k(G)$, is the graph where vertices represent the $k$-colorings of $G$, and two $k$-colorings are joined by an edge if they differ in color on exactly one vertex. As a major problem in the field of reconfigurations for vertex colorings of graphs, the connectivity of $\mathcal{R}_k(G)$ has attracted widespread interest. In this talk, we will survey recent developments, particularly introducing relevant results on $P_\ell$-free graphs, along with some of our recent progress in this area.
