Maximize the number of independent sets of a fixed size

Let it(G) be the number of independent sets of size t in a graph G. Engbers and Galvin asked how large it(G) could be in graphs with minimum degree at least δ. They further conjectured that when n≥ 2δ and t≥ 3, it(G) is maximized by the complete bipartite graph Kδ, n-δ . This conjecture has drawn the attention of many researchers recently. In this talk, we prove this conjecture.
Joint work with Po-Shen Loh and Benny Sudakov.
