Application of reproducing kernel method for solving nonlinear fredholm-volterra integrodifferential equations

This paper investigates the numerical solution of nonlinear Fredholm-Volterra integro-differential equations using reproducing kernel Hilbert space method. The solution ux is represented in the form of series in the reproducing kernel space. In the mean time, the n-term approximate solution u _n(x) is obtained and it is proved to converge to the exact solution ux. Furthermore, the proposed method has an advantage that it is possible to pick any point in the interval of integration and as well the approximate solution and its derivative will be applicable. Numerical examples are included to demonstrate the accuracy and applicability of the presented technique. The results reveal that the method is very effective and simple.
