Green's relations and regularity on some subsemigroups of transformations that preserve equivalences
Let $T(X)$ be the full transformation semigroup on a set $X$. For two equivalence relations $E$ and $F$ on $X$ with $F \subseteq E$, let
Keywords:
$T(X, E, F) = \{ \alpha \in T(X) : \forall x, y \in X, (x y)\in E \Rightarrow (x\alpha, y\alpha) \in F \}. $,
