$\widetilde{\mathbf{A}}_{1}$型zigzag代数Hochschild上同调的Batalin-Vilkovisky结构
Batalin-Vilkovisky structure on Hochschild cohomology of zigzag algebra of type $\widetilde{\mathbf{A}}_{1}$
摘要：
本文研究了$\widetilde{\mathbf{A}}_{1}$型量子锯齿代数$A_{q}$的Hochschild上同调上的Batalin-Vilkovisky结构.我们首先计算了$A_{q}$的霍赫希尔德同调群和Hochschild上同调群的维数。在此基础上，我们确定了$A_{q}$的Hochschild上同调环，并明确给出了$A_{q}$的Hochschild上同调环上的Batalin-Vilkovisky算子和Gerstenhaber括号.
英文摘要：
In this paper, we study the Batalin-Vilkovisky structure on the Hochschild cohomology of quantum zigzag algebras $A_{q}$ of type $\widetilde{\mathbf{A}}_{1}$. We first calculate the dimensions of Hochschild homology groups and Hochschild cohomology groups of $A_{q}$. Based on these computations, we determine the Hochschild cohomology ring of $A_{q}$, and give the Batalin-Vilkovisky operator and the Gerstenhaber bracket on Hochschild cohomology ring of $A_{q}$ explicitly.
