Controllability of time varying semilinear non-instantaneous impulsive systems with delay, and nonlocal conditions [PDF]

open access: yesArchives of Control Sciences, 2022
In this paper we prove the exact controllability of a time varying semilinear system considering non-instantaneous impulses, delay, and nonlocal conditions occurring simultaneously.

On some existence results of mild solutions for nonlocal integrodifferential Cauchy problems in Banach spaces [PDF]

open access: yesOpuscula Mathematica, 2011
In this paper, we study a class of integrodifferential evolution equations with nonlocal initial conditions in Banach spaces. Existence results of mild solutions are proved for a class of integrodifferential evolution equations with nonlocal initial ...

Mathematical Models with Nonlocal Initial Conditions: An Exemplification from Quantum Mechanics

open access: yesMathematical and Computational Applications, 2021
Nonlocal models are ubiquitous in all branches of science and engineering, with a rapidly expanding range of mathematical and computational applications due to the ability of such models to capture effects and phenomena that traditional models cannot ...

Functional differential equations with nonlocal initial conditions [PDF]

open access: yesInternational Journal of Stochastic Analysis, 1996
We study the existence, uniqueness, asymptotic properties, and continuous dependence upon data of solutions to a class of abstract nonlocal Cauchy problems. The approach we use is based on the theory of m‐accretive operators and related evolution equations in Banach spaces.

A nonlocal problem for loaded partial differential equations of fourth order

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
A nonlocal problem for the fourth order system of loaded partial differential equations is considered. The questions of a existence unique solution of the considered problem and ways of its construction are investigated.

Fractional parabolic problems with a nonlocal initial condition [PDF]

open access: yesMoroccan Journal of Pure and Applied Analysis, 2017
Abstract In this work we will consider a class of non local parabolic problems with nonlocal initial condition, more precisely we deal with the problem where is a bounded domain, the function a can be a singular potential, g is a suitable function which will be specified ...
