Braided Hochschild cohomology and Hopf actions
Cris Negron
We show that the braided Hochschild cohomology, of an algebra in a suitably algebraic braided monoidal category, admits a graded ring structure under which it is braided commutativ…

The Gerstenhaber bracket as a Schouten bracket for polynomial rings extended by finite groups
Cris Negron, Sarah Witherspoon
We apply new techniques to Gerstenhaber brackets on the Hochschild cohomology of a skew group algebra formed from a polynomial ring and a finite group (in characteristic 0). We sho…
