.The main goal of this article is to provide an approximate solution for two-dimensional fractional integral differential equations using orthogonal Lagrange polynomials, which is widely used in engineering problems. The obtained results show the efficiency and effectiveness of the method and also show the ability of the method to numerically solve some nonlinear models such as nonlinear partial differential equations that have special applications in engineering and nonlinear science problems. First, the shifted orthogonal Lagrange polynomials are defined and the properties of these polynomials are presented. Integration operation matrix and product operation matrix are introduced. Then, these properties are used together with two-dimensional nodes with weak single kernels using Lagrange polynomials to convert the given integral equation to solving nonlinear algebraic equations. Numerical examples are included to demonstrate the validity and applicability of the new method. The obtained results show the efficiency and effectiveness of the method and also show the ability of the method to numerically solve some nonlinear models such as nonlinear partial differential equations that have special applications in engineering and nonlinear science problems. | ||
