Abstract

In this article, we continue our study of category dynamical systems, that is functors ss from a category GG to \Top\op\Top^{\op}, and their corresponding skew category algebras. Suppose that the spaces s(e)s(e), for e\ob(G)e \in \ob(G), are compact Hausdorff. We show that if (i) the skew category algebra is simple, then (ii) GG is inverse connected, (iii) ss is minimal and (iv) ss is faithful. We also show that if GG is a locally abelian groupoid, then (i) is equivalent to (ii), (iii) and (iv). Thereby, we generalize results by \"{O}inert for skew group algebras to a large class of skew category algebras.
