遗传Artin代数的导等价

Derived equivalences for hereditary Artin algebras

Donald Stanley, Adam-Christiaan van Roosmalen

摘要:

我们研究了塞尔函子在导出等价理论中的作用。设$\mathcal{A}$是一个阿贝尔范畴,$(\mathcal{U}, \mathcal{V})$是有界导出范畴$D^b \mathcal{A}$上的一个$t$ -结构,该范畴具有心$\mathcal{H}$ .我们调查时,自然嵌入$\mathcal{H} \to D^b \mathcal{A}$可以扩展到一个三角形等价$D^b \mathcal{H} \to D^b \mathcal{A}$。我们的研究重点是$\mathcal{A}$是有限维遗传代数上的有限维模范畴的情况。在这种情况下,我们证明了这样的扩展存在的当且仅当$t$-结构是有界的和过道$\mathcal{U}$的$t$下的Serre函子是封闭的。

英文摘要:

We study the role of the Serre functor in the theory of derived equivalences. Let $\mathcal{A}$ be an abelian category and let $(\mathcal{U}, \mathcal{V})$ be a $t$-structure on the bounded derived category $D^b \mathcal{A}$ with heart $\mathcal{H}$. We investigate when the natural embedding $\mathcal{H} \to D^b \mathcal{A}$ can be extended to a triangle equivalence $D^b \mathcal{H} \to D^b \mathcal{A}$. Our focus of study is the case where $\mathcal{A}$ is the category of finite-dimensional modules over a finite-dimensional hereditary algebra. In this case, we prove that such an extension exists if and only if the $t$-structure is bounded and the aisle $\mathcal{U}$ of the $t$-structure is closed under the Serre functor.
