报告摘要：

Ramsey type problem has been a hot topic in mathematics for decades now due to their intrinsic beauty, wide applicability, and overwhelming difficulty despite somewhat misleadingly simple statements. A coloring of a graph is called rainbow if no two edges have the same color. Colorings of complete graphs that contain no rainbow triangle have very interesting and somewhat surprising structure. Gallai first examined this structure under the guise of transitive orientations. In this talk, we will introduce the concepts of Ramsey and Gallai-Ramsey numbers. Some recent results will be also given.
