题目： Anti-Ramsey problems in complete bipartite graphs
摘要： A subgraph $H$ of an edge-colored graph $G$ is rainbow if all of its edges have different colors. The anti-Ramsey number is the maximum number of colors in an edge-coloring of $G$ with no rainbow copy of $H$. Originally a complete graph was considered as $G$. In this talk, we consider a complete bipartite graph as the host graph and discuss some results for the graph $H$ being hamiltonian cycle, perfect matching and spanning tree, respectively.
