报告题目A survey of Berge-Turán hypergraph problems

报告简介This is a literature review report on the Turán type extremal problem of Berge hypergraph. Since 2003, scholars have studied the Turán number of Berge hypergraph of cycles, paths, and trees. In recent years, Győri et al. and Davoodi et al. extended the Erdős-Gallai Theorem on paths to Berge paths. Then, we will introduce some results about the Turán problems of Berge hypergraphs on uniform hypergraphs such as Berge trees,Berge-K2,t , Begre-C2k, Berge complete graphs. And also, we introduce some general lemmas for Berge-Turán hypergraph problems.
