Let [Formula: see text] be a nonempty subset of [Formula: see text]. The invariant subsemigroup of the full transformation semigroup [Formula: see text] is denoted by [Formula: see text] In this paper, we characterize the regularity of the following

Higgins [‘The Mitsch order on a semigroup’, Semigroup Forum 49 (1994), 261–266] showed that the natural partial orders on a semigroup and its regular subsemigroups coincide. This is why we are interested in the study of the natural partial orde

For a semigroup $S$, let ${S}^{1} $ be the semigroup obtained from $S$ by adding a new symbol 1 as its identity if $S$ has no identity; otherwise let ${S}^{1} = S$. Mitsch defined the natural partial order $\leqslant $ on a semigroup $S$ as follows:
