Emil Sköldberg
The homologies of monomial ideals and incidence algebras.
* Wednesday 25 October 2017,   15:15,   M2 (M233)
Given a set of monomials M ={m_1, ..., m_r} in a polynomial ring, one can form the set L of all least common multiples of subsets of M. This set is a partially ordered set, (even a lattice) ordered by divisibility. It is known that the betti numbers of the ring S/(M) can be computed as the homology of the simplicial complex of L. In the talk, I will explain how this relationship can be lifted to hold on the level of resolutions, between modules over S on one hand, and modules over the incidence algebra of L on the other hand.
