报告摘要:
At a high level, the problem of chromatic threshold studies the `complexity' of a dense graph without a forbidden subgraph. This topic has received considerable attention as it connects this extremal problem with graphs coloring and also transversals of hypergraphs with bounded VC dimension. In this talk, I will discuss some recent work in this direction, discovering new connections to combinatorial convexity and the problem of chi-boundedness in structural graph theory.
