Title: Local cohomology of thickenings

Abstract: Let $R$ be a standard graded polynomial ring that is finitely generated over a field, and let $I$ be a homogenous prime ideal of $R$.  A recent paper of Bhatt, Blickle, Lyubeznik, Singh, and Zhang examined the local cohomology of the thickenings $R/I^t$ in characteristic $0$, and provided a stabilization result for these cohomology modules. I will explicitly construct isomorphisms between local cohomology modules of thickenings in several cases.
