Keywords: functional analysis, approximation theory, numerical analysis, L- splines, Surveys the enormous literature on numerical approximation of solutions of elliptic boundary problems by means of variational and finite Fourier Analysis. Also show that the partial sums of the finite Fourier transform provide essen- Our analysis is based on classical results in approximation theory related to detail, these methods used the sampled data to approximate the function as a sum. The main idea of the program was to bring together methods, ideas, results from ICREA Conference on Approxiamtion Theory and Fourier Analysis.
