Hochschild Cohomology Groups of the Zn Graded Algebras
Translated Abstract
In this note the definition of Hochschild cohomology groups of Zn-graded algebras is given, and the low dimensional Hochschild cohomology groups are described. Moreover, a necessary and sufficient condition for a Zn-graded algebra to be a graded separable algebra is given in terms of the first Hochschild cohomology group, and the one-to-one correspondence between the zero degree component of the second Hochschild cohomology group and the Hochschild extensions of A is obtained.
