Finite nilsemigroups with modular congruence lattices
Alexander L. Popovich Ural Federal University, Ekaterinburg, Russia
Abstract:
This paper continues the joint work [2] of the author with P. Jones. We describe all finitely generated nilsemigroups with modular congruence lattices: there are 91 countable series of such semigroups. For finitely generated nilsemigroups a simple algorithmic test to the congruence modularity is obtained.
Keywords:
Semigroup, Nilsemigroup, Congruence lattice.
