A Unified Approach to Some Classes of Nonlinear Integral Equations

open access: yesJournal of Function Spaces, 2014
We are going to discuss some important classes of nonlinear integral equations such as integral equations of Volterra-Chandrasekhar type, quadratic integral equations of fractional orders, nonlinear integral equations of Volterra-Wiener-Hopf type, and ...

On Monotonic and Nonnegative Solutions of a Nonlinear Volterra-Stieltjes Integral Equation

open access: yesJournal of Function Spaces, 2014
We study the existence of monotonic and nonnegative solutions of a nonlinear quadratic Volterra-Stieltjes integral equation in the space of real functions being continuous on a bounded interval. The main tools used in our considerations are the technique

Infinite point and Riemann–Stieltjes integral conditions for an integro-differential equation

open access: yesNonlinear Analysis, 2019
In this paper, we study the existence of solutions for two nonlocal problems of integro-differential equation with nonlocal infinite-point and Riemann–Stieltjes integral boundary conditions. The continuous dependence of the solution will be studied.

A new theorem on the existence of the Riemann-Stieltjes integral and an improved version of the Lo\'eve-Young inequality

open access: yes, 2015
Using the notion of the truncated variation we obtain a new theorem on the existence and estimation of the Riemann-Stieltjes integral. As a special case of this theorem we obtain an improved version of the Lo\'{e}ve-Young inequality for the Riemann ...

Existence and Uniqueness of Positive Solutions for a New System of Fractional Differential Equations

open access: yesDiscrete Dynamics in Nature and Society, 2020
By virtue of a recent existing fixed point theorem of increasing φ−h,e-concave operator by Zhai and Wang, we consider the existence and uniqueness of positive solutions for a new system of Caputo-type fractional differential equations with Riemann ...
