# Cyclic cohomology of the Weyl algebra

Willwacher, Thomas (2015). Cyclic cohomology of the Weyl algebra. Journal of Algebra, 425:277-312.

## Abstract

We give an explicit formula for sp$_{2n}$-basic representatives of the cyclic cohomology of the Weyl algebra HC•(A$_{2n}$).As an application, we prove a generalization of a theorem of Nest and Tsygan concerning the relation of the Todd class and the cyclic cohomology of the differential operators on a complex manifold.

## TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
