Polyharmonicity and algebraic support of measures

Ognyan Kounchev, Hermann Render

We introduce a multivariate Markov transform which generalizes the well-known one-dimensional Stieltjes transform from the Moment problem and Spectral theory. Our main result state…

Padé approximation for a multivariate Markov transform

Ognyan Kounchev, Hermann Render

Methods of Padé approximation are used to analyse a multivariate Markov transform which has been recently introduced by the authors, and which is generalizing the well-known in Spe…
