Idempotent-Separating Congruences on Inverse ${\Gamma}-Semigroups$
Arindam Seth · Kyungpook mathematical journal · 1997
A characterization of the maximum idempotent-separating congruence on an inverse was given by Saha [3]. Here we first give an alternate characterization of the maximum idempotent-separating congruence on an inverse and then we give a description of the lattice of idempotents-separating congruences on an inverse .
