Green’s relations and regularity for semigroups of transformations with restricted range that preserve double direction equivalence relations

© 2019 by the Mathematical Association of Thailand. All rights reserved. Let T(X) be the full transformation semigroup on a set X. For an equivalence E on X and a nonempty subset Y of X, let (Formula Presented). In this article, we give a necessary and sufficient condition for TE*(X, Y) to be a subs...
