pi-Regularity of Semigroup Graded Rings
, 2002 The notion of pi-regularity is a generalization of von Neumann regularity. In this paper we begin our investigation of pi-regular and strongly pi-regular semigroup graded rings.

On the compatibility of the natural order on a regular semigroup
, 1983 SynopsisA notable achievement in the algebraic theory of semigroups has been the discovery by Nambooripad of the natural order on a regular semigroup. He has shown that this order is compatible with multiplication if and only if the semigroup is locally ...

Matrix groups and regular semigroups
Let Tn denote the tranformation semigroup consisting of all maps from [n] → [n], where [n] = {1, . . . , n}. In 2009, Ara´ujo, Mitchell and Schneider gave a classification of subgroups G ≤ Sn such that ⟨G, a⟩ is a regular semigroup for all a ∈ Tn ...

On intra-regular ordered semigroups
Semigroup Forum, 1993 The author continues her studies of partially ordered semigroups \(S\) which are intraregular, that is, for every \(a\in S\) there are \(x,y\in S\) such that \(a\leq xa^ 2 y\) [see the author, Semigroup Forum 44, 341-346 (1992; Zbl 0756.06008)]. It is shown (similar to the purely semigroup theoretical case) that a p.o.

On residual finiteness of monoids, their Schützenberger groups and associated actions
, 2014 RG was supported by an EPSRC Postdoctoral Fellowship EP/E043194/1 held at the University of St Andrews, Scotland.In this paper we discuss connections between the following properties: (RFM) residual finiteness of a monoid M ; (RFSG) residual finiteness ...

THE ANALOGUE OF WEIGHTED GROUP ALGEBRA FOR SEMITOPOLOGICAL SEMIGROUPS [PDF]
Journal of Sciences, Islamic Republic of Iran, 1995 In [1,2,3], A. C. Baker and J.W. Baker studied the subspace Ma(S) of the convolution measure algebra M, (S) of a locally compact semigroup. H. Dzinotyiweyi in [5,7] considers an analogous measure space on a large class of C-distinguished topological ...

On the Bifree Locally Inverse Semigroup
, 1995 A class of regular semigroups closed under taking direct products, regular subsemigroups, and homomorphic images is an existence variety, (or e-variety) of regular semigroups.

Amenability and Weak Amenability of the Semigroup Algebra l^1 (〖 S〗_T )
پژوهشهای ریاضی, 2016 Let S be a semigroup with a left multiplier on S. A new product on S is defined by related to S and such that S and the new semigroup ST have the same underlying set as S. It is shown that if is injective then where, is the extension of on Also, we

Robust observability for regular linear systems under nonlinear perturbation
Electronic Journal of Differential Equations, 2015 In this article, we consider the admissibility and exact observability of a class of semilinear systems obtained by nonlinear perturbation for regular linear systems.
