Structure of the Semigroup of Semigroup Extensions [PDF]
Transactions of the American Mathematical Society, 1971 Let B B denote a compact semigroup with identity and G G a compact abelian group. Let Ext ( B , G ) \operatorname {Ext} (B,G) denote the semigroup of extensions of G G by B B . We show that Ext

Quantitative recurrence for free semigroup actions [PDF]
, 2016 We consider finitely generated free semigroup actions on a compact metric space and obtain quantitative information on Poincaré recurrence, average first return time and hitting frequency for the random orbits induced by the semigroup action. Besides, we

On Maximal Subgroups of Free Idempotent Generated Semigroups [PDF]
, 2011 We prove the following results: (1) Every group is a maximal subgroup of some free idempotent generated semigroup. (2) Every finitely presented group is a maximal subgroup of some free idempotent generated semigroup arising from a finite semigroup.

Specification and thermodynamical properties of semigroup actions [PDF]
, 2015 In the present paper, we study the thermodynamical properties of finitely generated continuous subgroup actions. We propose a notion of topological entropy and pressure functions that do not depend on the growth rate of the semigroup and introduce strong

Pseudo-amenability and pseudo-contractibility of restricted semigroup algebra
Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2018 In this article the pseudo-amenability and pseudo-contractibility of restricted semigroup algebra lr1(S) and semigroup algebra, l1(Sr) on restricted semigroup, Sr are investigated for different classes of inverse semigroups such as Brandt semigroup, and ...

FUZZY SEMIGROUPS IN REDUCTIVE SEMIGROUPS [PDF]
Korean Journal of Mathematics, 2013 Summary: We consider a fuzzy semigroup \(S\) in a right (or left) reductive semigroup \(X\) such that \(S(k)=1\) for some \(k \in X\) and find a faithful representation (or anti-representation) of \(S\) by transformations of \(S\). Also we show that a fuzzy semigroup \(S\) in a weakly reductive semigroup \(X\) such that \(S(k)=1\) for some \(k \in X ...

Max-plus fundamental solution semigroups for a class of difference Riccati equations [PDF]
, 2015 Recently, a max-plus dual space fundamental solution semigroup for a class of difference Riccati equation (DRE) has been developed. This fundamental solution semigroup is represented in terms of the kernel of a specific max-plus linear operator that ...

Introducing Fully Up-Semigroups
Discussiones Mathematicae - General Algebra and Applications, 2018 In this paper, we introduce some new classes of algebras related to UP-algebras and semigroups, called a left UP-semigroup, a right UP-semigroup, a fully UP-semigroup, a left-left UP-semigroup, a right-left UP-semigroup, a left-right UP-semigroup, a ...
