Bernoulli polynomials collocation for weakly singular Volterra integro-differential equations of fractional order

Abstract

This paper is concerned with a numerical procedure for fractional Volterra integro-differential equations with weakly singular kernels. The fractional derivative is in the Caputo sense. In this study, Bernoulli polynomials of first kind is used and its matrix form is given. Then, the matrix form based on the
collocation points is constructed for each term of the problem. Hence, the proposed scheme simplifies the problem to a system of algebraic equations. Error analysis is also investigated. Numerical examples are announced to demonstrate the valadity of the method.
