A Groupoid Approach to Discrete Inverse Semigroup Algebras [PDF]
, 2009 Let $K$ be a commutative ring with unit and $S$ an inverse semigroup. We show that the semigroup algebra $KS$ can be described as a convolution algebra of functions on the universal \'etale groupoid associated to $S$ by Paterson.

Neutrosophic Left Almost Semigroup [PDF]
Neutrosophic Sets and Systems, 2014 In this paper we extend the theory of neutrosophy to study left almost semigroup shortly LAsemigroup. We generalize the concepts of LA-semigroup to form that for neutrosophic LA-semigroup.

Frequently Hypercyclic and Chaotic Behavior of Some First-Order Partial Differential Equation
Abstract and Applied Analysis, 2013 We study a particular first-order partial differential equation which arisen from a biologic model. We found that the solution semigroup of this partial differential equation is a frequently hypercyclic semigroup.

THE ÉTALE GROUPOID OF AN INVERSE SEMIGROUP AS A GROUPOID OF FILTERS [PDF]
Journal of the Australian Mathematical Society, 2011 Paterson showed how to construct an étale groupoid from an inverse semigroup using ideas from functional analysis. This construction was later simplified by Lenz.

On transformation semigroups which are ℬ𝒬-semigroups
International Journal of Mathematics and Mathematical Sciences, 2006 A semigroup whose bi-ideals and quasi-ideals coincide is called a ℬ𝒬-semigroup. The full transformation semigroup on a set X and the semigroup of all linear transformations of a vector space V over a field F into itself are denoted, respectively, by T(X)

Difference of composition operators on weighted Bergman spaces over the half-plane
Journal of Inequalities and Applications, 2016 Recently, the bounded, compact and Hilbert-Schmidt difference of composition operators on the Bergman spaces over the half-plane are characterized in (Choe et al. in Trans. Am. Math. Soc., 2016, in press).

The cone of functionals on the Cuntz semigroup [PDF]
, 2011 The functionals on an ordered semigroup S in the category Cu--a category to which the Cuntz semigroup of a C*-algebra naturally belongs--are investigated.

Combinatorial Gelfand models for some semigroups and q-rook monoid algebras [PDF]
, 2007 Inspired by the results of [R. Adin, A. Postnikov, Y. Roichman, Combinatorial Gelfand model, preprint math.RT arXiv:0709.3962], we propose combinatorial Gelfand models for semigroup algebras of some finite semigroups, which include the symmetric inverse ...

Pi Semigroup Algebras of Linear Semigroups [PDF]
Proceedings of the American Mathematical Society, 1990 It is well-known that if a semigroup algebra K [ S ] K[S] over a field K K satisfies a polynomial identity then the semigroup S S has the permutation property. The converse is not true in general even when S S is a group.

ON INVERSE SEMIGROUP C ∗ -ALGEBRAS AND CROSSED PRODUCTS [PDF]
, 2011 We describe the C -algebra of an E-unitary or strongly 0- E-unitary inverse semigroup as the partial crossed product of a commu- tative C -algebra by the maximal group image of the inverse semigroup.
