Polya conditions for multivariate Birkhoff interpolation: from general to rectangular sets of nodes. (English) Zbl 1212.65039

This paper deals with the study of uniform Birkhoff schemes with a rectangular set of nodes. Polya conditions on these schemes are presented. The authors also recall and re-interpret the standard Polya conditions and show that they arise because of a very simple reason. Some examples are presented.
