Singular Hochschild Cohomology and Gerstenhaber Algebra Structure
Zhengfang Wang ;
Date 2 Aug 2015
AbstractIn this paper, we define the singular Hochschild cohomology groups $HH_{sg}^i(A, A)$ of an associative $k$-algebra $A$ as morphisms from $A$ to $A[i]$ in the singular category $D_{sg}(Aotimes_k A^{op})$ for $iin mathbb{Z}$. We prove that $HH_{sg}^*(A, A)$ has a Gerstenhaber algebra structure and in the case of a symmetric algebra $A$, $HH_{sg}^*(A, A)$ is a Batalin-Vilkovisky (BV) algebra.
