报告内容简介：In general, it is difficult to give the Gerstenhaber algebraic structure on the Hochschild cohomolohy of an algebra. In this talk, we consider the Hochschild cohomolohy of Z2xZ2-Galois covering algebra of quantum exterior algebra with two variables. We give the graded commutative ring structure and the Gerstenhaber algebraic structure on the Hochschild cohomolohy of this algebra.
