关于Koszul代数与Yoneda代数的导出等价的存在性

On the existence of a derived equivalence between a Koszul algebra and its Yoneda algebra

R. M. Aquino, E. N. Marcos, Sonia Trepode

摘要:

本文主要研究Koszul代数和Yoneda代数的导出范畴之间的关系,特别是考虑它们是三角等价的情况.证明了单连通Koszul代数与其Yoneda代数是导出等价的。考虑了导离散Koszul代数,给出了这类Koszul代数与其Yoneda代数导等价的充要条件.最后,我们看看Koszul代数,使他们导出等价于遗传代数。在遗传代数是驯服的情况下,我们刻画了这些代数何时导出等价于它们的Yoneda代数。

英文摘要:

In this paper we focus on the relations between the derived categories of a Koszul algebra and its Yoneda algebra, in particular we want to consider the cases where these categories are triangularly equivalent. We prove that the simply connected Koszul algebras are derived equivalent to their Yoneda algebras. We consider derived discrete Koszul algebras, and we give necessary and sufficient conditions for these Koszul algebras to be derived equivalent to their Yoneda algebras. Finally, we look at the Koszul algebras such that they are derived equivalent to a hereditary algebra. In the case that the hereditary algebra is tame, we characterize when these algebras are derived equivalent to their Yoneda algebras.
