Applications of Homomorphism on the Structure of Semigroups


By utilizing homomorphisms and -strong semilattice of semigroups, we show that the Green (*,~)-relation H*,~ is a regular band congruence on a r-ample semigroup if and only if it is a G-strong semilattice of completely J*,~-simple semigroups. The result generalizes Petrichs result on completely regular semigroups with Greens relation H a normal band congruence or a regular band congruence from the round of regular semigroups to the round of r-ample semigroups.
