稳定无穷范畴上的t-结构

t-structures on stable infinity-categories

Fosco Loregian

摘要:

目前的工作重新制定的经典理论的t-结构减少经典的定义 *Faisceaux Pervers* 到一个相当原始的范畴小工具:合适的反射因子分解系统。这种翻译是唯一可能的,由于无穷范畴设置的优点。一旦t-结构的基本理论得到发展,一个自然的研究方向是在“torsio-centric”的视角下对t-结构进行全面的处理:我们将因子分解系统的技术应用于Postnikov塔理论,证明t-结构的心脏的abelianity,以及Bridgeland稳定条件的理论。

英文摘要:

The present work re-enacts the classical theory of t-structures reducing the classical definition given in *Faisceaux Pervers* to a rather primitive categorical gadget: suitable reflective factorization systems. This translation is only possible due to the virtues of the infinity-categorical setting. Once the basic theory of t-structure has been developed, a natural direction of research is to develop a comprehensive treatment of t-structure in the "torsio-centric" perspective: we apply the technology of factorization systems to the theory of Postnikov towers, to the proof of the abelianity of the heart of a t-structure, and to the theory of Bridgeland's stability conditions.
