可达范畴理论中的对偶性

Dualities in the theory of accessible categories

Giacomo Tendas

AI总结:

本文通过弱可靠权类的概念,将涉及可达范畴的多种已知对偶性统一为一般对偶定理的实例,将其扩展至富化环境,并探讨了由此产生的新对偶性。

摘要:

通过弱可靠权类的概念,我们将许多涉及带有选定极限类的可达范畴的已知对偶性,作为一般对偶定理的实例加以恢复。这些包括局部有限可表范畴的 Gabriel-Ulmer 对偶性、局部有限多可表范畴的 Diers 对偶性,以及有限可达范畴的 Makkai-Paré 对偶性。在此过程中,我们将这些结果扩展到富化环境,为该理论提供了一种更形式化和统一的方法,并讨论了作为我们主定理结果而产生的新对偶性。

英文摘要:

Through the notion of weakly sound class of weights, we recover many known dualities involving accessible categories with a chosen class of limits, as instances of a general duality theorem. These include the Gabriel-Ulmer duality for locally finitely presentable categories, Diers duality for locally finitely multipresentable categories, and the Makkai-Paré duality for finitely accessible categories. In doing so, we extend these to the enriched setting, provide a more formal and unifying approach to the theory, and also discuss new dualities that arise as a consequence of our main theorem.
