Twisted products: Enveloping actions and equivariant absolute neighborhood extensors

Luis Martínez, Héctor Pinedo

The classical notion of twisted product is studied in the context of partial actions, in particular, we show that the globalization of a partial action is a twisted product. In add…

Partial actions of groups on generalized matrix rings

Dirceu Bagio, Héctor Pinedo

Let $n$ be a positive integer and $R = (M_{ij})_{1 \leq i, j \leq n}$ be a generalized matrix ring. For each $1 \leq i, j \leq n$ , let $I_{i}$ be an ideal of the ring $R_{i} := M_{ii}$ and denot…

A topological correspondence between partial actions of groups and inverse semigroup actions

Luis Martínez, Héctor Pinedo, Carlos Uzcátegui

We present some generalizations of the well-known correspondence, found by R. Exel, between partial actions of a group $G$ on a set $X$ and semigroup homomorphism of $S (G)$ on the…
