Abstract

For a non-empty set X, let P(X)  represent the partial transformation semigroup on X. For a non-empty subset Y of X, define gif.latex?{\small\overline{PT}(X,Y)}  as the semigroup 


gif.latex?\overline{PT}(X,Y)=\{\alpha\in&space;P(X)&space;:(\operatorname{dom}\alpha\cap&space;Y)\alpha\subseteq&space;Y&space;\}.


Then gif.latex?{\small\overline{PT}(X,Y)}  is a generalization of P(X) , encompassing all partial transformations on  that maintain Y as an invariant set. This paper delves into exploring the characterization of coregular elements within gif.latex?{\small\overline{PT}(X,Y)} and applies the results to obtain a similar characterization in relevant semigroups.
