Hochschild cohomology: some methods for computations
... and H 1 (A, A) = 0, see [18]. The importance of the simply connected algebras follows from the fact that usually we may reduce the study of indecomposable modules over an algebra to that for the corresponding simply connected algebras, using Galois coverings. Despite this very little is known about ...
