报告摘要:

A subgraph H of an edge-colored graph G is rainbow if all of its edges havedifferent colors. The anti-Ramsey number is the maximum number of colors in anedge-coloring of G with no rainbow copy of H. Originally a complete graph wasconsidered as $G$. In this talk, we consider a complete bipartite graph as thehost graph and discuss some results for the graph H  being hamiltonian cycle, perfect matching andspanning tree, respectively.
