关于行为类似无穷Dynkin型簇范畴的三角剖分范畴及其与无穷边形三角剖分的关系

On a triangulated category which behaves like a cluster category of infinite Dynkin type, and the relation to triangulations of the infinity-gon

Thorsten Holm, Peter Jorgensen

摘要:

本文研究了一类2-Calabi-Yau三角范畴D,其Auslander-Reiten代数为ZA_{\infty} .我们表明,集群倾斜子类别D形成一个所谓的集群结构,我们对这些子类别进行分类,人们可以称之为“三角的无穷大,去”。这让人想起A_n型的簇范畴C,它是一个2-Calabi-Yau三角范畴,其Auslander-Reiten是ZA_n的商。C的簇倾斜子范畴形成一个簇结构,并根据(n+3)-边形的三角剖分进行分类。类别D的行为类似于“A_{\infty}类型的群集类别”。

英文摘要:

This paper investigates a certain 2-Calabi-Yau triangulated category D whose Auslander-Reiten quiver is ZA_{\infty}. We show that the cluster tilting subcategories of D form a so-called cluster structure, and we classify these subcategories in terms of what one may call `triangulations of the infinity-gon'. This is reminiscent of the cluster category C of type A_n which is a 2-Calabi-Yau triangulated category whose Auslander-Reiten quiver is a quotient of ZA_n. The cluster tilting subcategories of C form a cluster structure and they are classified in terms of triangulations of the (n+3)-gon. The category D behaves like a `cluster category of type A_{\infty}'.
