Given a finite-dimensional algebra and , we construct a new algebra , called the stretched algebra, and relate the homological properties of and . We investigate Hochschild cohomology and the finiteness condition (Fg), and use stratifying ideals to show that has (Fg) if and only if has (Fg). We also consider projective resolutions and apply our results in the case where is a -Koszul algebra for some .

Hochschild 上同调、有限性条件和 d-Koszul 代数的推广
给定一个有限维代数和, 我们构造一个新的代数, 称为拉伸代数, 并将其同调性质联系起来和. 我们研究 Hochschild 上同调和有限性条件(Fg),并使用分层理想来证明有(Fg)当且仅当有(Fg)。我们还考虑投影分辨率并将我们的结果应用于以下情况是一个-Koszul 代数.
