Abstract

The present paper proposes a fast numerical method for the linear Volterra integral equations with
regular and weakly singular kernels having smooth solutions. This method is based on the approx-
imation of the kernel, to simplify the integral operator and then discretization of the simpli ed
operator using a forward di erence formula. To analyze and verify the accuracy of the method, we
examine sample and benchmark problems with known exact solutions.
