If you have a question about this talk, please contact ibl10. In this talk I will discuss some recent work examining the extremal relationship between two well-studied graph parameters: the order of the largest homogeneous set in a graph G and the maximal number of distinct degrees appearing in an induced subgraph of G, denoted respectively by hom (G) and f(G). Our main theorem improves estimates due to Bukh and Sudakov and to Narayanan and Tomon and shows that if G is an n-vertex graph with hom (G) at least n The relationship between these parameters is known to change when hom (G) < n{1/2}. I hope to discuss the suspected relationship in this other region, along with supporting results. Joint work with Laurentiu Ploscaru.
