Abstract
Polya conditions are certain algebraic inequalities that regular Birkhoff
interpolation schemes must satisfy, and they are useful in deciding if a given scheme
is regular or not. Here we review the classical Polya condition and then we show
how it can be strengthened in the case of rectangular nodes.
