Minimizing the number of copies of Kr in a Ks-saturated graph

Abstract:

Graph saturation is one of the oldest areas of investigation in extremal combinatorics. A graph G is called F-saturated if G does not contain a subgraph isomorphic to F, but the addition of any edge creates a copy of F. We resolve the most fundamental question of minimizing the number of cliques of size r in a Ks-saturated graph for all sufficiently large numbers of vertices, confirming a conjecture of Kritschgau, Methuku, Tait and Timmons. We further prove a corresponding stability result. Joint work with Po-Shen Loh.

Before the talk, at 3:10pm, there will be tea and cookies in Wean 6220.
