A Note on the Greatest Idempotent-separating Congruence and Group Congruences on a Weakly Inverse Semigroup
Xu Mang · Journal of Sichuan Normal University · 2002
In this note, we give some corrections and simplifications of the main results on the greatest idempotent separating congruence and group congruences on a weakly inverse semigroup in the literature (J. Sichuan Normal University(Natural Science),2001,24(3):219～223.).
