Multivariate Vandermonde matrices with separated nodes on the unit circle are stable

Stefan Kunis, Dominik Nagel, Anna Strotmann

We prove explicit lower bounds for the smallest singular value and upper bounds for the condition number of rectangular, multivariate Vandermonde matrices with scattered nodes on t…
