Simplicial resolutions for the second power of square-free monomial ideals

Commutative Algebra 2021-03-12 v2

Abstract

Given a square-free monomial ideal II, we define a simplicial complex labeled by the generators of I2I^2 which supports a free resolution of I2I^2. As a consequence, we obtain (sharp) upper bounds on the Betti numbers of the second power of any square-free monomial ideal.
