On Γ-embeddings and partial actions of function spaces

Abstract

This paper deals with the extension of partial actions of topological groups on topological spaces. Within this framework, we introduce a class of topological embeddings defined via the inverse semigroup of homeomorphisms between open subsets of a topological space. We describe several embeddings of this type, referred to as $\hat{I}“$- embeddings, and we place particular emphasis on one of them. In particular, we prove that every topological space $Y$ admits a $\hat{I}“$-embedding into the space of continuous functions $C(X,Y)$, equipped with the compact-open topology, where $X$ is a compact space. Consequently, any partial action $\hat{I}¸$ of a topological group $G$ on $Y$ naturally induces a partial action $\hat{\hat{I}}¸$ on $C(X,Y).$ Throughout the paper, we investigate various relationships between these actions, as well as between their corresponding globalizations and enveloping spaces.
