On left quasinormal orthodox semigroups
Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 1983SynopsisThe existence of a smallest inverse congruence on an orthodox semigroup is known. It is also known that a regular semigroupSis locally inverse and orthodox if and only if there exists a local isomorphism fromSonto an inverse semigroupT.In this paper, we show the existence of a smallestR-unipotent congruence ρ on an orthodox semigroupSand give ...

\(\Gamma\)-orthodox semigroups
1994Summary: The notion of \(\Gamma\)-semigroups was introduced by M. K. Sen and N. K. Saha in the year 1986, they also introduced the concept of orthodox \(\Gamma\)-semigroup in 1990. In this paper we introduce \(\Gamma\)-orthodox semigroups and \(\Gamma\)-regular semigroups and present some basic properties of these \(\Gamma\)-semigroups.
