Geometry-Driven Conditioning of Multivariate Vandermonde Matrices in High-Degree Regimes

Omer Friedland, Yosef Yomdin

We study multivariate monomial Vandermonde matrices $V_{N} (Z)$ with arbitrary distinct nodes $Z = {z_{1}, \dots, z_{s}} \subset B_{2}^{n}$ in the high-degree regime $N \geq s - 1$ . Introducing a pr…

Algebraic Reconstruction of Piecewise-Smooth Functions of Two Variables from Fourier Data

Michael Levinov, Yosef Yomdin, Dmitry Batenkov

We investigate the problem of reconstructing a 2D piecewise smooth function from its bandlimited Fourier measurements. This is a well known and well studied problem with many real…
