On summability of weighted Lagrange interpolation.: II (Freud-type weights)

The aim of this paper is to continue our investigations started in [15], where we studied the summability of weighted Lagrange interpolation on the roots of orthogonal polynomials with respect to a weight function w. Starting from the Lagrange interpolation polynomials we constructed a wide class of discrete processes which are uniformly convergent in a suitable Banach space (C-rho, parallel to(.)parallel to(rho)) of continuous functions (rho denotes (another) weight). In [15] we formulated several conditions with respect to w,rho, (C-rho, parallel to(.)parallel to(rho)) and to summation methods for which the uniform convergence holds. The goal of this part is to study the special case when w and p are Freud-type weights. We shall show that the conditions of results of [15] hold in this case. The order of convergence will also be considered.
