We do so by extending the techniques developed by Munn in (Proc R Soc Edinbur Sect A 107:175-196, 1987) and (Proc R Soc Edinbur Sect A 115:109-117, 1990) for the study of semigroup rings of inverse semigroups. Restriction, weakly ample and ample semigroups are considered.engAmple semigroupInverse skeletonPseudofinite semilatticeRestriction semigroupSemigroup ring(Semi)prime(Semi)primitivejournal article10.1007/s00233-014-9612-1
