This paper investigates the convergence condition for the polynomial approximation of rational functions and rational curves. The main result, based on a hybrid expression of rational functions (or curves), is that two-point Hermite interpolation converges if all eigenvalue moduli of a certain r\_r

In this paper we find an algorithm which computes the Hilbert function of schemes Z of ''fat points'' in ‫ސ‬ 3 whose support lies on a rational normal cubic curve C. The algorithm shows that the maximality of the Hilbert function in degree Ε½ t is related to the existence of fixed curves either C its
