Abstract

For a nonempty set X , let T ( X ) be the total transformation semigroup on X . In this paper, we consider the subsemigroups of T ( X ) which are defined by T ( X , Y ) = { α ∈ T ( X ) : X α ⊆ Y } and S ( X , Y ) = { α ∈ T ( X ) : Y α ⊆ Y } where Y is a non-empty subset of X . We characterize the left regular and right regular elements of both T ( X , Y ) and S ( X , Y ) . Moreover, necessary and sufficient conditions for T ( X , Y ) and S ( X , Y ) to be left regular and right regular are given. These results are then applied to determine the numbers of left and right regular elements in T ( X , Y ) for a finite set X .
