Soft ideals and soft filters of soft ordered semigroups

open access: yes, 2011
It is shown that soft ordered semigroups over an ordered semigroup are actually soft ordered subsemigroups of (S,A). Soft idealistic semigroups over an ordered semigroup are soft ideals of soft ordered semigroup (S,A).

Archimedean ordered semigroups as ideal extensions

open access: yes, 2009
The main result of the paper is a structure theorem concerning the ideal extensions of archimedean ordered semigroups. We prove that an archimedean ordered semigroup which contains an idempotent is an ideal extension of a simple ordered semigroup ...

Simplicial cohomology of totally ordered semigroup algebras [PDF]

open access: yes, 2012
PhD ThesisIt is known that some discrete semigroup algebras have trivial continuous simplicial cohomology, at least in high dimensions. The aim of this work is to investigate the situation for the locally compact case, which even for the important ...

Compact totally ℋ ordered semigroups

open access: yes, 1971
Compact totally H \mathcal {H} ordered semigroups are characterized. Each such semigroup is abelian and is, in fact, a closed subsemigroup of an I I -semigroup.

A partially ordered semigroup of Boolean spaces.

open access: yes, 1988
In this thesis we are concerned with arithmetic in a certain partially ordered, commutative semigroup D. The first chapter investigates the class of countable Boolean algebras from which this semigroup arises.

On generalized fuzzy ideals of ordered LA-semigroups [PDF]

open access: yes, 2015
The left, right and intra-regular classes of an ordered semigroup play an essential role in studying the structural properties of the associative structure.

Derivations from Totally Ordered Semigroup Algebras into their Duals

open access: yes, 1997
For a well-behaved measureμ, on a locally compact totally ordered setX, with continuous partμc, we makeLp(X,μc) into a commutative Banach bimodule over the totally ordered semigroup algebraLp(X,μ), in such a way that the natural surjection from the ...
