Title: Combinatorics of finite sets III: Kruskal-Katona theorem

Time & Venue:  20211020日周三上午 9:00-10:30

Abstract:

In extremal set theory, a deep and powerfull result is the  Kruskal–Katona theorem, which  describes the size of shadows of set families.  This theorem induces a short proof of the Erdos-Ko-Rado theoremmotivated by which we shall give an analogue of finite linear vector spaces
