Speaker: Sepehr Hajebi Institution: University of Waterloo Location: MC 5479

Abstract: We prove that there exists a function f such that, for every positive integer c, every graph with no induced five-vertex path contains either a clique on c+1 vertices or a set of at most f(c) vertices which intersects all maximum stable sets in G.
