Green's relations on Croisot-Teissier semigroups
Green's relation \({\mathcal L}\), \({\mathcal R}\), \({\mathcal J}\), \({\mathcal H}\) and \({\mathcal D}\) on an arbitrary Croisot-Teissier semigroup S are characterized. Hence necessary and sufficient conditions are obtained for S to have only principal ideals or to be bisimple.
