Generalized Polynomials on Semigroups

open access: yesAnnales Mathematicae Silesianae
This article has two main parts. In the first part we show that some of the basic theory of generalized polynomials on commutative semi-groups can be extended to all semigroups.

Radicals of semigroup rings of commutative semigroups

open access: yesSemigroup Forum, 1994
This is a survey of results on radicals of semigroup rings of commutative semigroups. Most of the material is concerned with the Jacobson radical, but some other classical radicals and the general Kurosh-Amitsur radicals are also discussed. There are five sections that deal with: 1) descriptions of the radicals, 2) semiprimitivity, 3) nilness and ...

Weighted pseudo-almost periodic solutions for some neutral partial functional differential equations

open access: yesElectronic Journal of Differential Equations, 2012
In this article we study the existence of weighted pseudo almost periodic solutions of an autonomous neutral functional differential equation with Stepanov-Weighted pseudo almost periodic terms in a Banach space.

Semigroup compactifications by generalized distal functions and a fixed point theorem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1991
The notion of “Semigroup compactification” which is in a sense, a generalization of the classical Bohr (almost periodic) compactification of the usual additive reals R, has been studied by J. F. Berglund et. al. [2].

On fuzzy points in semigroups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We consider the semigroup S¯ of the fuzzy points of a semigroup S, and discuss the relation between the fuzzy interior ideals and the subsets of S¯ in an (intra-regular) semigroup S.
