报告摘要：Motivated by anti-Ramsey numbers introduced by Erdos, Simonovits and Sos in 1975, we study the anti-Ramsey problem when host graphs are plane triangulations and hypergraphs. In this talk, we will present some recent results on anti-Ramsey numbers for graphs and hypergraphs, including planar anti-Ramsey numbers of paths and matchings, and anti-Ramsey numbers of paths and cycles in hypergraphs.
