Hochschild cohomology ring of a maximal order of the quaternion algebra
Abstract
We give an efficient bimodule projective resolution of a maximal Z-order Λ of the ordinary quaternion algebra over Q, and therefore we determine the ring structure of the Hochschild cohomology of Λ by calculating the Yoneda products using this resolution.
