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.

Solutions for a category of singular nonlinear fractional differential equations subject to integral boundary conditions

open access: yesBoundary Value Problems, 2022
We concentrate on a category of singular boundary value problems of fractional differential equations with integral boundary conditions, in which the nonlinear function f is singular at t = 0 $t=0$ , 1.

Convergence analysis of product integration method for nonlinear weakly singular Volterra-Fredholm integral equations [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2015
In this paper, we studied the numerical solution of nonlinear weakly singular Volterra-Fredholm integral equations by using the product integration method. Also, we shall study the convergence behavior of a fully discrete version of a product integration
