摘要：
A class of numerical methods is developed for second order Volterra integro-differential equations by using a Legendre spectral approach. We provide a rigorous error analysis for the proposed methods, which shows that the numerical errors decay exponentially in the L-infinity-norm and L-2-norm. Numerical examples illustrate the convergence and effectiveness of the numerical methods.
