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 Γ\Gamma- embeddings, and we place particular emphasis on one of them. In particular, we prove that every topological space YY admits a Γ\Gamma-embedding into the space of continuous functions C(X,Y)C(X, Y ), equipped with the compact-open topology, where XX is a compact space. Consequently, any partial action θ\theta of a topological group GG on Y Y naturally induces a partial action θ^\hat\theta on C(X,Y).C(X, Y ). Throughout the paper, we investigate various relationships between these actions, as well as between their corresponding globalizations and enveloping spaces.
