On the idempotent-generated properties in singular semigroups
You Tai · Journal of Guizhou Normal University · 2002
Let I 1and I 2be subsets of the set of all idempotents of defect 1 in a finite full transformation semigroups.In this note,by the graph properties,we characterize the conditions under which the generated subsemigroups I 1and I 2are isomorphic.
