Presentations of inverse semigroups, their kernels and extensions [PDF]
, 2011 "Part of this work was done while Gray was an EPSRC Postdoctoral Research Fellow at the University of St Andrews, Scotland"Let S be an inverse semigroup and let π:S→T be a surjective homomorphism with kernel K.

F1000ResearchThroughout this paper our study focuses on transformation semigroups. These kinds of semigroups are the corner stone of semigroup theory. This is because every semigroup is isomorphic to transformation semigroup.

Some remarks on the domination between conjunctions and disjunctions
Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2007 There are diverse domination properties considered in linear programming, game theory, semigroup theory and graph theory. In this paper we present a class of conjunctions which dominate each triangular conorm.

Fractal and FractionalThe purpose of this work is to investigate the controllability of non-instantaneous impulsive (NII) Hilfer fractional (HF) neutral stochastic evolution equations with a non-dense domain. We construct a new set of adequate assumptions for the existence of

Existence of mild solutions for quasilinear integrodifferential equations with impulsive conditions
Electronic Journal of Differential Equations, 2009 We prove the existence and uniqueness of mild solutions of quasilinear integrodifferential equations with nonlocal and impulsive conditions in Banach spaces. The results are obtained by using a fixed point technique and semigroup theory. Examples are

Fractional Calculus for Non-Discrete Signed Measures
MathematicsIn this paper, we suggest a first-ever construction of fractional integral and differential operators based on signed measures including a vector-valued case. The study focuses on constructing the fractional power of the Riemann–Stieltjes integral with a

A semigroup approach to the Gnedenko system with single vacation of a repairman
, 2012 We investigate the Gnedenko system with one repairman who can take vacations. Our main focus is on the time asymptotic behaviour of the system. Using C 0-semigroup theory for linear operators we first prove the well-posedness of the system and the ...

Some decay results in Timoshenko beam with microtemperatures of type III
Boundary Value ProblemsThe governing equations of the thermoelastic Timoshenko beam with microtemperatures are derived based on type III entropy balance. Our development of this theory is prompted by the increasing use of materials that exhibit thermal variations at the ...
