Abstract.This paper chiefly takes into account the singularly perturbed delay Volterra-Fredholm integro-differential equations by numerically. In this context, firstly, priori estimates are given and a new discretization is constructed on piecewise-equidistant mesh by using interpolating quadrature rules [2] and composite integration formulas. Then, the convergence analysis and stability bounds of the presented method are discussed. Finally, numerical results are demonstrated with two test problems.Mathematics Subject Classification (2020): 65L1165L1265L2065L70Key words: Delay differential equationdifference schemeintegro-differential equationsingular perturbationuniform convergence
