Good congruence lattice on a kind of abundant semigroups
Qiang Zhao · Journal of Lanzhou University · 2005
Good congruence aggregates for the semilattice of cancellative monoids are introduced and the good congruences on these semigroups are characterized by means of good congruence aggregates. Furthermore, the meet and the join for the good congruence lattice are determined for the semilattice of commutative cancellative monoids.
