On quasi-orthodox semigroups with inverse transversals
T. S. Blyth, M. H. Almeida Santos · Proceedings of the Edinburgh Mathematical Society · 1997
An inverse transversal of a regular semigroup S is an inverse subsemigroup So that contains precisely one inverse of each element of S. Here we consider the case where S is quasi-orthodox. We give natural characterisations of such semigroups and consider various properties of congruences.
