Abstract:This paper deals with a special Hermite-Fejér interpolation process based at the zeros of generalized Freud polynomials which are orthogonal with respect to the weight w(x) = |x| α e −|x| β , x ̸ = 0, α > −1, β > 1. We prove its uniform convergence for functions belonging to a suitable space of functions equipped with a weighted uniform norm.
“…By contrast, in particular the Grünwald operator based at the zeros of orthonormal polynomials w.r.t. exponential weights has received few attention in literature [3,13,17].…”
We introduce special Hermite-Fejér and Grünwald operators at the zeros of the generalized Laguerre polynomials. We will prove that these interpolation processes are uniformly convergent in suitable weighted function spaces.
