SUBGROUPS OF THE FREE SEMIGROUP ON A BIORDERED SET IN WHICH PRINCIPAL IDEALS ARE SINGLETONS
Communications in Algebra, 2002ABSTRACT Easdown has conjectured that the subgroups of the free semigroup on an arbitrary biordered set are free. In this note a weaker conjecture is verified. It is shown that the subgroups of the free semigroup on a biordered set in which principal ideals are singletons are free.

Biordered Sets of Regular Semigroups with Inverse Transversals
Southeast Asian Bulletin of Mathematics, 2001In a regular semigroup \(S\), an inverse subsemigroup \(S^\circ\) of \(S\) is called an inverse transversal of \(S\) if \(S^\circ\) contains a unique inverse \(x^\circ\) of each element \(x\) of \(S\). The subject of this paper is the class of biordered sets of regular semigroups with inverse transversals, known throughout as IT-biordered sets.

CONSTRUCTION OF A R-STRONGLY UNIT REGULAR MONOID FROM A REGULAR BIORDERED SET AND A GROUP
Asian-European Journal of Mathematics, 2011In this paper we give a detailed study of R-strongly unit regular monoids. The relations between the biordered set of idempotents and the group of units in unit regular semigroups are better identified here. Conversely, starting from a regular biordered set E and a group G we construct a R-strongly unit regular semigroup S for which the set of ...
