Cohen-Macaulay and (S2) properties of the second power of squarefree monomial ideals
Speaker: Do Trong Hoang

Time: 9h30, Thursday, September 12, 2019
Location: Rom 611 - 612, Building A6, Institute of Mathematics

Abstractt: In this talk, we show that Cohen-Macaulay and (S2) properties are equivalent for the second power of an edge ideal. We also give an example a Gorenstein squarefree monomial ideal I such that S/I^2 satisfies the Serre condition (S2) but is not Cohen-Macaulay.
