TITLE: Asymptotic depth of invariant chains of edge ideals

ABSTRACT: We completely determine the asymptotic depth, equivalently, the asymptotic projective dimension of a chain of edge ideals that is invariant under the action of the monoid Inc of increasing functions on the positive integers. Our results and their proofs also reveal surprising combinatorial and topological properties of corresponding graphs and their independence complexes. In particular, we are able to determine the asymptotic behavior of all reduced homology groups of these independence complexes. This is joint work with T.Q. Hoa, D.T. Hoang, D.V. Le and T.T. Nguyen.
