EXISTENCE OF SOLUTION OF FUNCTIONAL VOLTERRA-FREDHOLM INTEGRAL EQUATIONS IN SPACE L∞((Formula presented)) AND SINC INTERPOLATION TO FIND SOLUTION Reza Arab, Mohsen Rabbani Journal of Integral Equations and Applications, 2022 A new measure of noncompactness (Mnc) and Darbo fixed point theorem are utilized on space L(R+) to prove the existence of solution for functional Volterra-Fredholm integral equations. An example is given to confirm the validity of results. Furthermore, we propound an iterative algorithm by Sinc interpolation to find the solution with an acceptable accuracy. In this algorithm, it does not need the problem is discretized to an algebraic system with unknown coefficients and we have an iterative processes to aproximate of solution with exponential convergence.
EXISTENCE OF SOLUTION OF FUNCTIONAL INTEGRAL EQUATIONS BY MEASURE OF NONCOMPACTNESS AND SINC INTERPOLATION TO FIND SOLUTION Mohsen Rabbani, Reza Arab, Bipan Hazarika, Nasser Aghazadeh Fixed Point Theory, 2022 In this article, we discuss the existence of solution for the functional integral equations in the Banach space BC(R + ) of real-valued continuous and bounded functions, using the method associated with the technique of measure of noncompactness and generalized Darbo fixed point theorem. We provide an example to illustrate our results, and we make an iterative algorithm by the Sinc interpolation to find solution to the above problem with acceptable accuracy.
Tripled fixed point results via a measure of noncompactness with applications Hemant Kumar Nashine, Reza Arab, Rabha W. Ibrahim Asian European Journal of Mathematics, 2021 In this paper, we create tripled fixed point outcomes via a subjective measure of noncompactness in the sense of Banas and Goebel. Furthermore, we introduce some applications of the measure of noncompactness notion to functional equations including nonlinear integral equations as well as local fractional integral equations.
Existence of Solution for Infinite System of Nonlinear Singular Integral Equations and Semi-Analytic Method to Solve it Bipan Hazarika, Mohsen Rabbani, Ravi P. Agarwal, Anupam Das, Reza Arab Iranian Journal of Science and Technology Transaction A Science, 2021 In this article, solvability of infinite system of nonlinear singular integral equations of two variables in Banach sequence spaces $$c_{0}$$ c 0 and $$\\ell _{1}$$ ℓ 1 is investigated. For this purpose, Hausdorff measure of noncompactness (in short, Hausdorff MNC) and Meir–Keeler condensing operators are employed. The guarantee of our results are given by some examples. Also to approach an approximation of semi-analytic solution, we introduce a coupled modified homotopy perturbation and Adomian decomposition method. Thus, an iterative algorithm is constructed to find the above solution. The numerical results show that the produced sequence to approximate the solution has a high accuracy.
