**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.
