Groupoids associated to semigroup actions

open access: yes, 2015
23 pagesIn this paper, we consider topological semigroup actions on compact topological spaces. Under mild assumptions on the semigroup and the action, we construct a semi-direct product groupoid with a Haar system.

Green's relations and regularity for semigroups of transformations that preserve reverse direction equivalence

open access: yes, 2011
Science and Technology Foundation of Guizhou Province, P.R. China [LKS [2010] 02]Let T(X) denote the full transformation semigroup on a set X. For an equivalence E on X, let T(there exists)(X) = {a is an element of T(X) : for all x, y is an element of X,

Green's relations and regularity for semigroups of transformations that preserve double direction equivalence

open access: yes, 2010
Let T(X) denote the full transformation semigroup on a set X. For an equivalence E on X, let T(E*)(X) = {alpha is an element of T(X) : for all x, y is an element of X, (x, y) is an element of E double left right arrow (x alpha, y alpha) is an element of ...
