Admissible closure operators and varieties of semilattice-ordered normal bands
It is known that varieties of semilattice-ordered semigroups are in one-to-one correspondence with the ordered pairs (p. [ ]) where p is a fully invariant congruence on the free semigroup on a countably infinite set and [ ] is a p-admissible closure operator. We find all admissible closure operators...

| 520 | 3 | |a It is known that varieties of semilattice-ordered semigroups are in one-to-one correspondence with the ordered pairs (p. [ ]) where p is a fully invariant congruence on the free semigroup on a countably infinite set and [ ] is a p-admissible closure operator. We find all admissible closure operators for varieties of left normal bands. Using the obtained results we describe all varieties of semilattice-ordered left normal bands by admissible closure operators. We solve the identity problem for all varieties of semilattice-ordered normal bands. | |
