One-Parameter Inverse Semigroups [PDF]
Transactions of the American Mathematical Society, 1972 This is the second in a projected series of three papers, the aim of which is the complete description of the closure of any one-parameter inverse semigroup in a locally compact topological inverse semigroup. In it we characterize all one-parameter inverse semigroups.

Abstract Boundary Delay Systems and Application to Network Flow
Mathematical Methods in the Applied Sciences, Volume 49, Issue 1, Page 119-129, 15 January 2026.ABSTRACT This paper investigates the well‐posedness and positivity of solutions to a class of delayed transport equations on a network. The material flow is delayed at the vertices and along the edges. The problem is reformulated as an abstract boundary delay equation, and well‐posedness is proved by using the Staffans–Weiss theory.

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.In this paper, the Yang transform Adomian decomposition method (YTADM) is employed in the solution of nonlinear time‐fractional coupled Burgers equations. The technique solves the fractional and nonlinear terms successfully via the Adomian decomposition of the Yang transform.

Module Amenability of Semigroup Algebras under Certain Module Actions
Journal of Mathematical Extension, 2014 In this paper we define a congruence ∼ on inverse semigroup S such that amenability of S is equivalent to amenability of S/ ∼. We study module amenability of semigroup algebra l 1 (S/ ∼) when S is an inverse semigroup with idempotents E and prove ...

Some Results on Smarandache Semigroups
Journal of Kufa for Mathematics and Computer, 2013 We discusse in this paper a Smarandache semigroups , a Smarandache cyclic semigroups and a Smarandache lagrange semigroups.We prove that the Smarandache semigroup with multiplication modulo 2P where p is an odd prime have two subgroups of order P-1and

On Partial C‐ and S‐Controllability Results for Semilinear Stochastic Systems
Journal of Function Spaces, Volume 2026, Issue 1, 2026.This article investigates the concepts of partial C‐ and S‐controllability for semilinear control systems that are disturbed by white noise. For these types of systems, it can be beneficial to study the deterministic and stochastic parts of the system separately, using a separation principle approach.

Idempotent 2x2 matrices over linearly ordered abelian groups [PDF]
Categories and General Algebraic Structures with ApplicationsIn this paper we study multiplicative semigroups of $2\times 2$ matrices over a linearly ordered abelian group with an externally added bottom element. The multiplication of such a semigroup is defined by replacing addition and multiplication by join and

Topological Aspects of Quadratic Graphs and M‐Polynomials Utilizing Classes of Finite Quasigroups
Journal of Mathematics, Volume 2026, Issue 1, 2026.Material science, drug design and toxicology studies, which relate a molecule’s structure to its numerous properties and activities, are studied with the use of the topological index. Graphs with finite algebraic structure find extensive applications in fields such as mathematics, elliptic curve cryptography, physics, robotics and information theory ...
