Title: Revisiting the Feigin-Tsygan isomorphism
Date: Tue, Dec 10, 2019, 13:15 - 14:45
Place: Seminar Room A
Abstract: We review the 'loop spaces and connections' approach to the Feigin-Tysgan isomorphism between two-periodic de Rham cohomology and periodic cyclic homology, and discuss the compatibility of the isomorphism with the Hodge and the Hochschild-Kostant-Rosenberg filtrations. This is part of a larger project with Nick Rozenblyum studying the relation between commutative and non-commutative calculus.
