Abstract |
|
Newman and Rivlin have shown that there is a 1-1 correspondence between the nodes and weights of the n-th order divided difference of n-th degree polynomials. Their method applies only to polynomials. In this paper we develop a new approach and apply it to extend their results to the setting of Extended Complete Tchebycheff Systems. |
