摘要

一元三角范畴的巴尔默谱是一种重要的几何构造,它与厚张量理想的分类问题密切相关。我们证明,从有限张量范畴 C 的德林菲尔德中心到 C 的遗忘函子扩展到它们对应的稳定范畴之间的一元三角函子,并在它们的巴尔默谱之间诱导出一个连续映射。我们给出了它是注入式、投射式或同构的条件。我们运用这一一般理论证明,与有限维共三边简单准霍普夫代数(特别是特征除以群的阶的群代数)相关联的巴尔默谱与它们的德林费尔德倍相关联的巴尔默谱重合,而且这两个范畴的厚理想是双射的。对于某些本森-威瑟斯庞粉碎共积霍普夫布拉斯,也证明了类似的定理,这些布拉斯一般不是类三角形的。

Balmer spectra and Drinfeld centers

The Balmer spectrum of a monoidal triangulated category is an important geometric construction which is closely related to the problem of classifying thick tensor ideals. We prove that the forgetful functor from the Drinfeld center of a finite tensor category C to C extends to a monoidal triangulated functor between their corresponding stable categories, and induces a continuous map between their Balmer spectra. We give conditions under which it is injective, surjective, or a homeomorphism. We apply this general theory to prove that Balmer spectra associated to finite-dimensional cosemisimple quasitriangular Hopf algebras (in particular, group algebras in characteristic dividing the order of the group) coincide with the Balmer spectra associated to their Drinfeld doubles, and that the thick ideals of both categories are in bijection. An analogous theorem is proven for certain Benson–Witherspoon smash coproduct Hopf algebras, which are not quasitriangular in general.

期刊介绍: ANT’s inclusive definition of algebra and number theory allows it to print research covering a wide range of subtopics, including algebraic and arithmetic geometry. ANT publishes high-quality articles of interest to a broad readership, at a level surpassing all but the top four or five mathematics journals. It exists in both print and electronic forms. The policies of ANT are set by the editorial board — a group of working mathematicians — rather than by a profit-oriented company, so they will remain friendly to mathematicians'' interests. In particular, they will promote broad dissemination, easy electronic access, and permissive use of content to the greatest extent compatible with survival of the journal. All electronic content becomes free and open access 5 years after publication.
