The Source of Semiprimeness of Semigroups
Journal of Mathematics, 2021 In this study, we define new semigroup structures using the set SS=a∈S|aSa=0 which is called the source of semiprimeness for a semigroup S with zero element.

The Booleanization of an inverse semigroup [PDF]
Semigroup Forum, 2018 We prove that the forgetful functor from the category of Boolean inverse semigroups to the category of inverse semigroups with zero has a left adjoint. This left adjoint is what we term the ‘Booleanization’.

On the Structure Space of a Г -Semigroup Via Its Left Operator Semigroup
Discussiones Mathematicae - General Algebra and Applications, 2022 The structure space of a semigroup endowed with hull kernel topology is introduced and studied. Also the structure space of a Г -semigroup is defined and a homeomorphism has been established between structure space of a Г -semigroup and the structure ...

Semigroup Forum, 2016 We define the notion of the partial order of ends of the Cayley graph of a semigroup. We prove that the structure of the ends of a semigroup is invariant under change of finite generating set and at the same time is inherited by subsemigroups and extensions of finite Rees index.

Mathematical Methods in the Applied Sciences, Volume 46, Issue 1, Page 1178-1184, 15 January 2023., 2023 In this paper, we discuss the study of some signal processing problems within Bayesian frameworks and semigroups theory, in the case where the Banach space under consideration may be nonseparable. For applications, the suggested approach may be of interest in situations where approximation in the norm of the space is not possible.

In memoriam: Marco Avellaneda (1955–2022)
Mathematical Finance, Volume 33, Issue 1, Page 3-15, January 2023., 2023 Abstract Marco Avellaneda (1955–2022) was a leading figure in the development of mathematical modeling in finance and its dissemination among market practitioners. We provide a sketch of his trajectory and outline some of his main research contributions to mathematical finance.

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

Group key management based on semigroup actions [PDF]
arXiv.org, 2015 In this work we provide a suite of protocols for group key management based on general semigroup actions. Construction of the key is made in a distributed and collaborative way.

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

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
