纯极小投射化解析与格子的完美模

Pure minimal injective resolutions and perfect modules for lattices

Tal Gottesman, Viktória Klász, Markus Kleinau, Rene Marczinzik

AI总结:

本文研究了分布格子的纯极小投射化解析条件,并分类了完美反链模,揭示了格子理论与同调代数之间的联系。

摘要:

在最近的一篇文章中,Iyama和Marczinzik证明了一个格子是分布的当且仅当发生代数是Auslander正则的,从而建立了同调代数与格子理论之间的新联系。在本文中,我们研究何时一个分布格子具有纯极小投射化解析,这一概念最初由Ajitabh、Smith和Zhang提出并研究。我们会发现,这个问题自然引导我们研究某些反链模何时是完美模。我们在假设这些完美反链模的 canonical 反链解析是最小的情况下,对完美反链模进行了分类,并利用这一结果,以格子理论术语对分布格子的 incidence 代数的纯极小投射化解析进行了完整分类。我们利用这些结果回答了Ajitabh、Smith和Zhang提出的问题,证明存在没有纯投射化解析的Auslander-Gorenstein多项式恒等环。

英文摘要:

In a recent article, Iyama and Marczinzik showed that a lattice is distributive if and only if the incidence algebra is Auslander regular, giving a new connection between homological algebra and lattice theory. In this article we study when a distributive lattice has a pure minimal injective coresolution, a notion first introduced and studied in a work of Ajitabh, Smith and Zhang. We will see that this problem naturally leads to studying when certain antichain modules are perfect modules. We give a classification of perfect antichain modules under the assumption that their canonical antichain resolution is minimal and use this to give a completion classification in lattice theoretic terms of incidence algebras of distributive lattices with pure minimal injective coresolution. We use our results to answer a question raised by Ajitabh, Smith and Zhang by showing that there exist Auslander-Gorenstein polynomial identity rings without a pure injective coresolution.
