摘要

本文研究了交换noether环模范畴内的强生成。我们建立了这样的环在其模类内具有强发生器的准则,解决了Iyengar和Takahashi提出的问题。因此,这不仅证明了任何有限Krull维的noether拟优环都满足这一准则,而且也适用于该类以外的环。此外,我们在模范畴内确定了素特征环的显式强生成器,并根据模的经典数值不变量建立了Rouquier维的上界。

Strong generation for module categories
This article investigates strong generation within the module category of a commutative Noetherian ring. We establish a criterion for such rings to possess strong generators within their module category, addressing a question raised by Iyengar and Takahashi. As a consequence, this not only demonstrates that any Noetherian quasi-excellent ring of finite Krull dimension satisfies this criterion, but applies to rings outside this class. Additionally, we identify explicit strong generators within the module category for rings of prime characteristic, and establish upper bounds on Rouquier dimension in terms of classical numerical invariants for modules.

期刊介绍: The Journal of Pure and Applied Algebra concentrates on that part of algebra likely to be of general mathematical interest: algebraic results with immediate applications, and the development of algebraic theories of sufficiently general relevance to allow for future applications.
