Vector-valued means and weakly almost periodic functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
A formula is set up between vector-valued mean and scalar-valued means that enables us translate many important results about scalar-valued means developed in [1] to vector-valued means.

Smarandache Soft Semigroups and their Properties

open access: yesJournal of New Theory, 2015
– In this paper, the notions of smarandache soft semigroups (SS-semigroups) introduced for the first time. An SS-semigroup ( , ) is basically a parameterized collection of subsemigroups which has F A is basically a parameterized collection of ...

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 \(

On representation of semigroups of inclusion hyperspaces

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2010
Given a group $X$ we study the algebraic structure of the compactright-topological semigroup $G(X)$ consisting of inclusionhyperspaces on $X$. This semigroup contains the semigroup$lambda(X)$ of maximal linked systems as a closed subsemigroup.We ...

On (m, n)-ideals and (m, n)-regular ordered semigroups [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2016
Let m, n be non-negative integers. A subsemigroup A of an ordered semigroup (S,  ,  is called an (m, n)-ideal of S if (i) Am SAn  A, and (ii) if x  A, y  S such that y  x, then y  A. In this paper, necessary and sufficient conditions for every (
