摘      要：In this paper we study the higher accuracy methods-the extrapolation and defect correction for the semidiscrete Galerkin approximations to the solutions of hyperbolicintegrodifferential equations. The global extrapolation and the correction approximationsof third order, rather than the pointwise extrapolation results, are derived.
