Resumen:
In this paper we study the convergence of a net of subspaces generated by dilations of polynomials in a nite dimensional subspace. As a consequence, we extend the results given by Zo and Cuenya [Proceedings of the Second International School. Advanced Courses of Mathematical Analysis II. (2007), 193-213] on a general approach to the problems of best vector-valued approximation on small regions from a nite dimensional subspace of polynomials.
