报告摘要:An edge-colored graph is calledrainbow graphif all the colors on its edges are distinct. Given a positive integer nand a graph G, the anti-Ramsey number ar(n,G) is defined to be the minimum number of colors rsuch that there exists a rainbow copy of Gin any exactly r-edge-coloring of K_n. Let F_{k,r} denote the graph by taking kcopies of K_rwith a vertex in common. In this talk, we determine the anti-Ramsey number ar(n,F_k) for large n..
