Local Gorenstein duality in chromatic group cohomology

Abstract

We consider local Gorenstein duality for cochain spectra C(BG;R)C^*(BG;R) on the classifying spaces of compact Lie groups GG over complex orientable ring spectra RR. We show that it holds systematically for a large array of examples of ring spectra RR, including Lubin-Tate theories, topological KK-theory, and various forms of topological modular forms. We also prove a descent result for local Gorenstein duality which allows us to access further examples.
