Sobolev orthogonal polynomials: Connection formulae

Abstract

This contribution aims to obtain several connection formulae for the polynomial sequence, which is orthogonal with respect to the discrete Sobolev inner product \[ \langle f, g\rangle_n=\langle {\bf u}, fg\rangle+ \sum_{j=1}^M \mu_{j} f^{(\nu_j)}(c_j) g^{(\nu_j)}(c_j), \] where \({\bf u}\) is a classical linear functional, \(c_j\in \mathbb R\), \(\nu_j\in \mathbb N_0\), \(j=1, 2,...., M\). The Laguerre case will be considered.
