整范畴的例子与非例子及容许交性质

Examples and non-examples of integral categories and the admissible intersection property

Souheila Hassoun, Amit Shah, Sven-Ake Wegner

摘要:

整范畴是前阿贝尔范畴的一个子类,Rump于2001年开始对它进行系统的研究。本文的第一部分主要讨论了几类拓扑向量空间和拓扑向量空间的积分问题。此外,我们还证明了整范畴类不包含在拟阿贝尔范畴类中,并且存在既不是整范畴也不是拟阿贝尔范畴的半阿贝尔范畴。在文章的最后一部分,我们证明了一个范畴是拟阿贝尔的当且仅当它有容许交,在这个意义上考虑最近由Br{ü}stle,Hassoun和Tattar。这表明在泛函分析中自然地产生了一类丰富的具有这种性质的非阿贝尔范畴.

英文摘要:

Integral categories form a sub-class of pre-abelian categories whose systematic study was initiated by Rump in 2001. In the first part of this article we determine whether several categories of topological and bornological vector spaces are integral. Moreover, we establish that the class of integral categories is not contained in the class of quasi-abelian categories, and that there exist semi-abelian categories that are neither integral nor quasi-abelian. In the last part of the article we show that a category is quasi-abelian if and only if it has admissible intersections, in the sense considered recently by Br{ü}stle, Hassoun and Tattar. This exhibits that a rich class of non-abelian categories having this property arises naturally in functional analysis.
