范畴上的部分作用

Partial Actions on Categories

Wagner Cortes, Miguel Ferrero, Eduardo Marcos

摘要:

本文引入了小$k$ -范畴上的部分作用的定义,推广了代数上类似的部分作用的概念。观点的部分行动,我们在本文中使用的是一个介绍了埃克塞尔在他的工作$C^*$ -代数,见\cite{E}。之后进行了各种概括,参见\cite{CJ, DEP, DE, DFP}。我们还定义了偏斜范畴的概念。我们证明了类似的结果在\cite{CM}。最后,我们给出了一个结果,给定的条件下,部分行动有一个全球化。

英文摘要:

In this paper we introduce the definition of partial action on small $k$-categories generalizing the similar well known notion of partial actions on algebras. The point of view of partial action which we use in this paper is the one which was introduced by Exel in his work on $C^*$-algebras, see \cite{E}. Various generalizations were done afterward, see \cite{CJ, DEP, DE, DFP}. Also we define the notion partial skew category. We prove similar results to the ones in \cite{CM}. Finally we show a result given conditions for a partial action to have a globalization.
