On the equivalence of three-dimensional differential systems

open access: yesOpen Mathematics, 2020
In this paper, firstly, we study the structural form of reflective integral for a given system. Then the sufficient conditions are obtained to ensure there exists the reflective integral with these structured form for such system.

Existence and uniqueness of a classical solution to a functional‐differential abstract nonlocal Cauchy problem

open access: yesInternational Journal of Stochastic Analysis, Volume 12, Issue 1, Page 91-97, 1999., 1998
The aim of this paper is to investigate the existence and uniqueness of a classical solution to a functional‐differential abstract nonlocal Cauchy problem in a general Banach space. For this purpose, a special kind of a mild solution is introduced and the Banach contraction theorem and a modified Picard method are applied.

Well posedness for evolution inclusions

open access: yesInternational Journal of Stochastic Analysis, Volume 7, Issue 4, Page 537-544, 1994., 1994
We prove the existence of a continuous selection of the multivalued map φ → Φ(φ) which is the set of all mild solutions of the evolution inclusion Here F is a multivalued map, Lipschitzian with respect to x, and A is the infinitesimal generator of a C0‐semigroup.

Coupled system of a fractional order differential equations with weighted initial conditions

open access: yesOpen Mathematics, 2019
Here, a coupled system of nonlinear weighted Cauchy-type problem of a diffre-integral equations of fractional order will be considered. We study the existence of at least one integrable solution of this system by using Schauder fixed point Theorem.

A novel algorithm for time-fractional foam drainage equation

open access: yesAlexandria Engineering Journal, 2020
In this work, we present a novel numerical algorithm for solving the nonlinear time-fractional foam drainage equation at early stages of the time. The analytical solution of the nonlinear time-fractional foam drainage equation is represented by a linear ...

Development of Aβ and anti-Aβ dynamics models for Alzheimer’s disease

open access: yesComputational and Mathematical Biophysics
Alzheimer’s disease is one of the most prevalent types of dementia worldwide. It is caused by the accumulation of amyloid-beta (Aβ) plaques in the brain, disrupting communication pathways and memory.
