CONGRUENCES ON REGULAR SEMIGROUPS RELATED WITH GREEN'S RELATIONS
Wang Li-min · Journal of South China Normal University · 2006
It is discussed the lattice of congruences on a regular semigroup generated by the congruences generated by Green's relations.Some degenerate cases of the Hasse diagram of this lattice are studied,and then these lattices on inverse semigroups and two special classes of completely regular semigroups are determined.
