  • The conditions unlder which a semnigroup ring is regu- lar (in the sense of von Neumann) are inlvestigated. SLufficient con- ditions are obtained in order that the semnigroup ring of an inverse semigroup be regular. Consequences of the regularity of the seni- group ring for the subgroups of the semigroup are established. The two results are then used to find necessary and sufficien-t conditions for the regularity of the semigroup ring when the semigroup is inverse and a union of groups. 1… CONTINUE READING
