A positive fixed point theorem with applications to systems of Hammerstein integral equations [PDF]

open access: yes, 2014
We present new criteria on the existence of fixed points that combine some monotonicity assumptions with the classical fixed point index theory. As an illustrative application, we use our theoretical results to prove the existence of positive solutions ...

A numerical solution of problem for essentially loaded differential equations with an integro-multipoint condition

open access: yesOpen Mathematics, 2022
We study a linear boundary value problem for systems of essentially loaded differential equations with an integro-multipoint condition. We make use of the numerical implementation of the Dzhumabaev parametrization method to obtain the desired result ...

Third-order differential equations with three-point boundary conditions

open access: yesOpen Mathematics, 2021
In this paper, a third-order ordinary differential equation coupled to three-point boundary conditions is considered. The related Green’s function changes its sign on the square of definition. Despite this, we are able to deduce the existence of positive

The Unique Solution to the Differential Equations of the Fourth Order with Non-Homogeneous Boundary Conditions

open access: yesJournal of Advances in Applied & Computational Mathematics, 2022
This research paper aims to establish the uniqueness of the solution to fourth-order nonlinear differential equations v(4)(x) + f (x,v(x)) = 0, x ε [a,b], with non-homogeneous boundary conditions where 0 ≤ a < ζ < b, the constants α, ????

Uniqueness of solutions for a ψ-Hilfer fractional integral boundary value problem with the p-Laplacian operator

open access: yesDemonstratio Mathematica, 2023
In this article, we discuss the existence of a unique solution to a ψ\psi -Hilfer fractional differential equation involving the pp-Laplacian operator subject to nonlocal ψ\psi -Riemann-Liouville fractional integral boundary conditions.
