用标准对偶a - bimodulehomk （a，K）给出域上有限维代数的Hochschild扩展代数。本文利用在Sköldberg意义上的二阶Hochschild同调群phh2 (a)，确定了tifa1的普通颤振是一个自内射Nakayama代数。
LetTbe a Hochschild extension algebra of a finite dimensional algebraAover a fieldKby the standard dualityA-bimoduleHomK(A,K). In this paper, we determine the ordinary quiver ofTifAis a self-injective Nakayama algebra by means of theℕ-graded second Hochschild homology groupHH2(A) in the sense of Sköldberg.
