一类Koszul自内射代数的柱脚变形的Hochschild上同调

Hochschild cohomology of socle deformations of a class of Koszul self-injective algebras

Nicole Snashall, Rachel Taillefer

摘要:

研究了广义Taft代数的Drinfeld二重化中一类Koszul自内射特殊双曲代数的形式变形所引起的柱脚变形.我们表明,对于这些变形,Hochschild上同调环模零是一个克鲁尔维数为2的生成的交换代数。

英文摘要:

We consider the socle deformations arising from formal deformations of a class of Koszul self-injective special biserial algebras which occur in the study of the Drinfeld double of the generalized Taft algebras. We show, for these deformations, that the Hochschild cohomology ring modulo nilpotence is a finitely generated commutative algebra of Krull dimension 2.
