A generalised interpolating post processing method for integral equation

Abstract

In [1], Interpolation post-processing method for integral equation was shown to be superior to the iteration method. This was also shown that it is of order O(h^2r+2). This paper describes the generalization in the choice of h, the mesh size, which leads to a higher order of O(h^pr+2) (where p=1,2,3,4 …) and hence an improved accuracy of the method.
