Reconstruction of Piecewise Smooth Multivariate Functions from Fourier Data
In some applications, one is interested in reconstructing a function <i>f</i> from its Fourier series coefficients. The problem is that the Fourier series is slowly convergent if the function is non-periodic, or is non-smooth. In this paper, we suggest a method for deriving high order ap...
