On some classes of generalized numerical semigroups

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
A generalized numerical semigroup is a submonoid of ℕd with finite complement in it. In this work we study some properties of three different classes of generalized numerical semigroups defined starting from numerical semigroups.

Stratified semigroups

open access: yesSemigroup Forum, 1995
A semigroup \(S\) with zero 0 is called stratisfied if \(\bigcap_{m > 0} S^ m = \{0\}\). (The definition is effective for any semigroup, that is, a semigroup \(S\) is stratisfied if \(S^ 0\) is stratisfied.) The depth function \(\lambda : S \setminus \{0\} \to N\) assigns to each \(s \in S\), \(s\neq 0\), the greatest positive integer \(m\) such that \(

THE DUALITY OF THE L?-REPRESENTATION ALGEBRA ?(S ) OF A FOUNDATION SEMIGROUP S AND FUNCTION ALGEBRAS [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2000
In the present paper for a large family of topological semigroups, namely foundation semigroups, for which topological groups and discrete semigroups are elementary examples, it is shown that ?(S) is the dual of a function algebra.
