拓扑理论的Stone对偶

Stone duality for topological theories

Dirk Hofmann, Isar Stubbe

摘要:

在范畴拓扑的背景下,更确切地说是T-范畴的背景下[Hofmann,2007],我们定义T-上极限的概念为V-范畴中的一个特定的上极限。一个完备且上完备的V-范畴,其中极限分布在T-上极限上,可以被认为是(上)框架在这个范畴水平上的推广。我们解释了关于T范畴的Stone对偶的一些概念,并证明T范畴的Cauchy完备性正是它的清醒性。

英文摘要:

In the context of categorical topology, more precisely that of T-categories [Hofmann, 2007], we define the notion of T-colimit as a particular colimit in a V-category. A complete and cocomplete V-category in which limits distribute over T-colimits, is to be thought of as the generalisation of a (co-)frame to this categorical level. We explain some ideas on a T-categorical version of "Stone duality", and show that Cauchy completeness of a T-category is precisely its sobriety.
