NUMERICAL SOLUTION OF VOLTERRA DELAY-INTEGRO-DIFFERENTIAL EQUATIONS VIA SPLINE/SPECTRAL METHODS

H.M. El-Hawary, K.A. El-Shami

Abstract


In this paper, we present a mixed spline/spectral method to solveVolterra delay-integro-differential equations (VDIDEs). This methodis based on generating the sextic spline collocation methods in allsubintervals. The approximation of the integration in thesesubintervals, can be calculated by the El-Gendi method. Convergenceresults of the present method are presented. Numerical results aregiven to illustrate the efficiency of the present method.
