Approximation of Polynomial Singularity Curves of Piecewise Polynomial Functions of Two Variables by Their Fourier-Jacobi Coefficients
In the present paper, we generalize the result obtained in an earlier paper by the author with respect to recovering the singularity curves of a piecewise constant function of two variables by its Fourier-Jacobi coefficients. The method is based on a modified Prony’s method suggested in an earlier paper by us for recov...
