On the rank of semigroup of transformations with restricted partial range
نویسندگان
چکیده
Let T(X) be the full transformation semigroup on a nonempty set X. For ? Z Y X, let T(X,Y,Z) = {? T(X):Y? Z}. It is not difficult to see that it generalized form of three well-known semigroups. This paper obtains an isomorphism theorem T(X,Y,Z). In addition, when X finite and rank calculated.

Regularity and Green's Relations on a Semigroup of Transformations with Restricted Range
Let T X be the full transformation semigroup on the setX and let T X,Y {α ∈ T X : Xα ⊆ Y}. Then T X,Y is a sub-semigroup of T X determined by a nonempty subset Y of X. In this paper, we give a necessary and sufficient condition for T X,Y to be regular. In the case that T X,Y is not regular, the largest regular sub-semigroup is obtained and this sub-semigroup is shown to determine the Green’s re...
