摘要/Abstract

摘要： 利用二元多项式代数的非分次Ore扩张构造一类三维斜Calabi-Yau代数,计算这类斜Calabi-Yau代数的Nakayama自同构,并建立其Hochschild同调和上同调的Van den Bergh对偶。

关键词: 斜Calabi-Yau代数, Van den Bergh对偶, Nakayama自同构, Ore扩张

Abstract: A class of three-dimensional skew Calabi-Yau algebras is constructed using ungraded Ore extensions of the polynomial algebra in two variables. The Nakayama automorphisms of these skew Calabi-Yau algebras are computed, and the Van den Bergh duality between their Hochschild homology and cohomology is established.

Key words: skew Calabi-Yau algebras, Van den Bergh duality, Nakayama automorphisms, Ore extensions
