The Fedder action and a simplicial complex of local cohomologies

Abstract: When $S$ is a ring of prime characteristic $p$ > 0, the local cohomology of $S$ carries a natural Frobenius structure. If $S$ is regular, we have access to Lyubeznik's powerful theory of F-modules. We lose this if $S$ is singular, but retain the notion of Frobenius actions. In this talk, we will present recent joint work with Eric Canton on some advantages to using a non-standard Frobenius action, defined when $S$ is a complete intersection ring, and will discuss applications to questions about finiteness properties.
