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.

Tight Representations of 0-𝐸-Unitary Inverse Semigroups

Abstract and Applied Analysis, 2011
We study the tight representation of a semilattice in {0,1} by some examples. Then we introduce the concept of the complex tight representation of an inverse semigroup 𝑆 by the concept of the tight representation of the semilattice of idempotents 𝐸 of 𝑆 ...

On inverse submonoids of the monoid of almost monotone injective co-finite partial selfmaps of positive integers

Karpatsʹkì Matematičnì Publìkacìï, 2019
In this paper we study submonoids of the monoid $\mathscr{I}_{\infty}^{\,\Rsh\!\!\nearrow}(\mathbb{N})$ of almost monotone injective co-finite partial selfmaps of positive integers $\mathbb{N}$.

Construction of propagators for divisible dynamical maps

New Journal of Physics, 2021
Divisible dynamical maps play an important role in characterizing Markovianity on the level of quantum evolution. Divisible maps provide an important generalization of Markovian semigroups. Usually one analyzes either completely positive or just positive

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 ...

Continuity and general perturbation of the Drazin inverse for closed linear operators

Abstract and Applied Analysis, 2002
We study perturbations and continuity of the Drazin inverse of a closed linear operator A and obtain explicit error estimates in terms of the gap between closed operators and the gap between ranges and nullspaces of operators.

Topological properties of C0 $C^{0}$-solution set for impulsive evolution inclusions

Boundary Value Problems, 2018
In this paper, we study the topological properties to a C0 $C^{0}$-solution set of impulsive evolution inclusions. The definition of C0 $C^{0}$-solutions for impulsive functional evolution inclusions is introduced.

Regularization of Nonhomogeneous Ill‐Posed Parabolic Cauchy Problems via a Two‐Parameter Method With Stability Estimates

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This study aims to propose a regularization method for an ill‐posed Cauchy problem involving an unbounded linear operator in a Hilbert space, in order to obtain a stable approximate solution together with error estimates. The main idea of the method developed in this study is to simultaneously perturb both the right‐hand side of the equation f(t) and ...

Spatial Decay Estimates for Elastic Plate System With Type II Heat Conduction

Journal of Mathematics, Volume 2026, Issue 1, 2026.
The classical Saint‐Venant principle has been extensively studied for harmonic and biharmonic models but remains largely unexplored for thermomechanical plates governed by hyperbolic (Type II) heat conduction, a conservative thermal model with unique dynamical features. This paper investigates the spatial decay properties of solutions to such a coupled

Isomorphism Theorems for Groupoids and Some Applications

International Journal of Mathematics and Mathematical Sciences, 2020
Using an algebraic point of view we present an introduction to the groupoid theory; that is, we give fundamental properties of groupoids as uniqueness of inverses and properties of the identities and study subgroupoids, wide subgroupoids, and normal ...
