Hypersurface support for noncommutative complete intersections
Cris Negron, Julia Pevtsova
We introduce an infinite variant of hypersurface support for finite-dimensional, noncommutative complete intersections. By a noncommutative complete intersection we mean an algebra…
Spectral Sequences for the Cohomology Rings of a Smash Product
Cris Negron
Stefan and Guichardet have provided Lyndon-Hochschild-Serre type spectral sequences which converge to the Hochschild cohomology and Ext groups of a smash product. We show that thes…
Computation of the Hochschild Cohomology Algebra of the Down-Up Algebra
Cris Negron
This document is supplementary material for the author's paper \emph{The cup product on hochschild cohomology for localizations of filtered koszul algebras}, arXiv:1304.0527. We gi…
The cup product on Hochschild cohomology via twisting cochains and applications to Koszul rings
Cris Negron
Given an acyclic twisting cochain , from a curved dg coalgebra to a dg algebra , we show that the associated twisted hom complex has cohomo…
