Lecture on “Bisections of Graphs Without Complete Bipartite Graphs”
Speaker: Hou Jianfeng, professor, doctoral supervisorDate: Wednesday, June 15, 2022Time: 9:0010:00Location: Tencent MeetingSponsor: School of Mathematics, Shandong UniversityAbstract:A bisection of a graph is a bipartition of its vertex set in which the two classes differ in size by at most one. For a random bisection of a graph with m edges, one expects m/4 edges spans in one vertex class. Bo...
