论文摘要

链复合物可以看作是与关系的某​​个颤抖的表示,$ q^{\ permatatorName {cpx}} $。顶点是整数,每个整数$ q $都有一个箭头$ q \ xrightArrow {} q-1 $,并且关系连续箭头构成$ 0 $。因此,经典的派生类别$ \ mathscr {d} $可以视为$ q^{\ permatatorName {cpx}} $的表示类别。 Iyama和Minamoto的见解是,$ \ Mathscr {d} $表现良好的原因是,被视为一个小类别,$ q^{\ permatatorName {cpx}} $具有serre functor。将$ \ mathscr {d} $的构造概括到具有serre functor的其他关系的其他Quivers中,导致$ q $形的派生类别$ {\ Mathscr {d}} _ q $。 利用Hovey和Gillespie的方法,我们在最近三篇论文中开发了$ {\ Mathscr {d}} _ q $的理论。本文简要介绍了$ {\ mathscr {d}} _ q $,该Q $针对已经熟悉经典派生类别的读者。

A chain complex can be viewed as a representation of a certain quiver with relations, $Q^{\operatorname{cpx}}$. The vertices are the integers, there is an arrow $q \xrightarrow{} q-1$ for each integer $q$, and the relations are that consecutive arrows compose to $0$. Hence the classic derived category $\mathscr{D}$ can be viewed as a category of representations of $Q^{\operatorname{cpx}}$. It is an insight of Iyama and Minamoto that the reason $\mathscr{D}$ is well behaved is that, viewed as a small category, $Q^{\operatorname{cpx}}$ has a Serre functor. Generalising the construction of $\mathscr{D}$ to other quivers with relations which have a Serre functor results in the $Q$-shaped derived category ${\mathscr{D}}_Q$. Drawing on methods of Hovey and Gillespie, we developed the theory of ${\mathscr{D}}_Q$ in three recent papers. This paper offers a brief introduction to ${\mathscr{D}}_Q$, aimed at the reader already familiar with the classic derived category.
