Quasi-Hyperbolicity and Delay Semigroups
Abstract and Applied Analysis, 2016 We study quasi-hyperbolicity of the delay semigroup associated with the equation u′(t)=Bu(t)+Φut, where ut is the history function and (B,D(B)) is the generator of a quasi-hyperbolic semigroup.

A Caputo fractional derivative of a function with respect to another function [PDF]
Communications in nonlinear science & numerical simulation, 2016 In this paper we consider a Caputo type fractional derivative with respect to another function. Some properties, like the semigroup law, a relationship between the fractional derivative and the fractional integral, Taylor’s Theorem, Fermat’s Theorem, etc.

Composition of Fractional Integral and Derivative Operators: Summarised in Tables
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT This paper compiles a complete, detailed list of composition properties for Riemann–Liouville fractional differintegrals, in all possible cases for orders anywhere in the complex plane, with the results presented clearly in a table for easy visual consumption.

On maximal subgroups of free idempotent generated semigroups
, 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.

International Journal of Mathematics and Mathematical Sciences, 2002 Let R be a ring. The circle operation is the operation a∘b=a+b−ab, for all a,b∈R. This operation gives rise to a semigroup called the adjoint semigroup or circle semigroup of R. We investigate rings in which the adjoint semigroup is regular. Examples are

ON HYBRID INTERIOR IDEALS IN SEMIGROUPS
Проблемы анализа, 2019 In this paper, we introduce the notion of hybrid interior ideals and hybrid characteristic interior ideals of a semigroup. We obtain some equivalent conditions for a hybrid structure to be a hybrid interior ideal of a semigroup.

On endomorphisms of groups of order 32 with maximal subgroups C24 or C42 ; pp. 1–14 [PDF]
Proceedings of the Estonian Academy of Sciences, 2016 It is proved that each group of order 32 that has a maximal subgroup isomorphic to C2 x C2 x C2 x C2 or C4 x C4 is determined by its endomorphism semigroup in the class of all groups.

CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT This paper proposes a boundary control method for nonlinear distributed parameter systems (DPSs) with limited boundary measurements (BMs), as typically encountered in networked cyber‐physical processes with spatially distributed dynamics such as thermal and biomedical diffusion systems.

Semigroups of Right Quotients of Topological Semigroups [PDF]
Transactions of the American Mathematical Society, 1970 Es sei \(S=(S, \cdot, \mathfrak S)\) eine topologische Halbgruppe und \(T= (T, \cdot) = Q_r(S,\Sigma)\) eine Rechtsquotientenhalbgruppe von \(S\) bezüglich einer Unterhalbgruppe \(\Sigma\) von \(S\). Gegenstand der Arbeit ist die Untersuchung von Topologien \(\mathfrak T\) auf \(T\), so daß \((T, \cdot, \mathfrak T)\) topologische Halbgruppe ist und \(\

On endomorphisms of groups of order 36; pp. 237–254 [PDF]
Proceedings of the Estonian Academy of Sciences, 2016 There exist exactly 14 non-isomorphic groups of order 36. In this paper we will prove that three of them are not determined by their endomorphism semigroups in the class of all groups.
