Twisted differential cohomology

DOI: 10.2140/agt.2019.19.1631
Abstract

We construct multiplicative twisted versions of differential cohomology theories for all highly structured ring spectra and twists. We prove existence and give a full classification of differential refinements of twists under mild assumptions. Various concrete examples are discussed and related to earlier approaches.
