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.
