Congruences on Menger algebras
arXiv:1305.6885 · doi:10.1080/00927872.2013.784979
Abstract
We discuss some types of congruences on Menger algebras of rank , which are generalizations of the principal left and right congruences on semigroups. We also study congruences admitting various types of cancellations and describe their relationship with strong subsets.
