A generalised interpolating post–processing method for integral equation
Interpolating post-processing method for integral equation has been demonstrated to be superior to the iteration method by Qun Lin, Shechua Zhang and Ningning Yan. They demonstrated that it is of order O (h2r+2) This paper describes the generalization in the choice of h, the mesh size which leads to a higher order of O (h2r+2)(where p = 2, 4, 6,... ) and hence an improved accuracy of the method.
