Abstract

In this article, we propose a numerical method based on alternative Legendre polynomials
for approximating the solutions of two-dimensional linear and nonlinear Volterra-Fredholm
integral equations. Alternative Legendre polynomials, known for their some special features
and simplicity in constructing operational matrices, provide an efficient basis for this method.
By employing the integration and product operational matrices of alternative Legendre polynomials,
the integral equations are reduced to a system of algebraic equations, simplifying
the computational process. Error analysis is conducted to assess the method’s accuracy, and
several examples are presented to validate the high precision and efficiency of the proposed
approach. The results confirm the accuracy and effectiveness of the method in solving complex
integral equations.
