Title: Cohen-Macaulayness of monomial ideals
Time: 2010-12-02 (Thu.)  15:00 - 16:00
Place: Auditorium, 6 Floor, Institute of Mathematics (NTU Campus)
Abstract: In this talk I will present a combinatorial criterion for the Cohen-Macaulayness of monomial ideals. This criterion helps to explain allmost all previous results on this topics. As an application, I will show that there are some striking relationships between the Cohen-Macaulayness of powers of Stanley-Reisner ideals and special classes of simplicial complexes (or hypergraphs).
