Abstract

This paper introduces a polynomial sinc-based collocation method, combined with Gauss-Legendre and Newton-Cotes quadrature rules to solve stochastic Volterra
integral equations (SVIEs) with a m-dimensional Brownian motion process. The proposed
technique employs Lagrange polynomial interpolation at sinc-type collocation nodes to
approximate the solution, thereby reducing the SVIE to a system of algebraic equations
that can be solved at low to moderate computational cost. A rigorous convergence analysis of the scheme is presented, and several numerical experiments are carried out to
illustrate its accuracy, efficiency, and reliability.
