| چکیده | ||
| This study investigates the solvability and approximation of fractional two-dimensional nonlinear functional integral equations in a Banach space. Motivated by the increasing relevance of fractional models in nonlinear sciences—including diffusion, viscoelasticity, and nonlinear wave propagation—we establish new existence results using a generalized Darbo fixed-point theorem combined with the measure of noncompactness. To validate the theory, an iterative Sinc-interpolation algorithm is developed, achieving exponential convergence for numerical approximation. The proposed approach not only generalizes existing one-dimensional results to higher dimensions but also provides a practical framework for analyzing soliton-type and other localized nonlinear structures in fractional systems. Numerical experiments confirm the accuracy and effectiveness of the method. | ||
