Quasi-ideal transversals of abundant semigroups and spined products

Al-Bar, Jehan and Renshaw, James (2011) Quasi-ideal transversals of abundant semigroups and spined products Semigroup Forum, 83, (3), pp. 522-537. (doi:10.1007/s00233-010-9223-4).

Record type: Article


We provide a new and much simpler structure for quasi-ideal adequate transversals of abundant semigroups in terms of spined products, which is similar in nature to that given by Saito for weakly multiplicative inverse transversals of regular semigroups [10]. As a consequence we deduce a similar result for multiplicative transversals of abundant semigroups and also consider the case when the semigroups are in fact regular and provide some new structure theorems for inverse transversals.
