剑桥英语官方网站摘要：In this article we show that an algebra A = K /(f(Xs)) has a periodic projective bimodule resolution of period 2, where K is the path algebra of the circular quiver with s vertices and s arrows over a commutative ring K, f(x) is a monic polynomial over K and X is the sum of all arrows in K. Moreover, by means of this projective bimodule resolution, we compute the Hochschild cohomology group of A, and we give a prentation of the Hochschild cohomology ring HH*(A) by the generators and the relations in the ca K is a field.
