A class of Runge–Kutta methods for nonlinear Volterra integral equations of the second kind with singular kernels

open access: yesAdvances in Difference Equations, 2018

Singularity Subtraction for Nonlinear Weakly Singular Integral Equations of the Second Kind [PDF]

open access: yes, 2019
The singularity subtraction technique for computing an approximate solution of a linear weakly singular Fredholm integral equation of the second kind is generalized to the case of a nonlinear integral equation of the same kind. Convergence of the sequence of approximate solutions to the exact one is proved under mild standard hypotheses on the ...

Two Singularity Subtraction Schemes for a Class of Nonlinear Weakly Singular Integral Equations

open access: yesNumerical Functional Analysis and Optimization, 2022
Singularity subtraction for linear weakly singular Fredholm integral equations of the second kind is generalized to nonlinear integral equations. Two approaches are presented: The Classical Ap proach discretizes the nonlinear problem, and uses some finite dimensional linearization process to solve numerically the discrete problem.

Monotonic solutions of functional integral and differential equations of fractional order

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2009
The existence of positive monotonic solutions, in the class of continuous functions, for some nonlinear quadratic integral equations have been studied by J. Banas. Here we are concerned with a singular quadratic functional integral equations.

On the Solution of Quadratic Nonlinear Integral Equation with Different Singular Kernels [PDF]

open access: yesMathematical Problems in Engineering, 2020
All the previous authors discussed the quadratic equation only with continuous kernels by different methods. In this paper, we introduce a mixed nonlinear quadratic integral equation (MQNLIE) with singular kernel in a logarithmic form and Carleman type. An existence and uniqueness of MQNLIE are discussed.
