A weighted transplantation theorem for Jacobi coefficients

Alberto Arenas, Óscar Ciaurri, Edgar Labarga

We present a transplantation theorem for Jacobi coefficients in weighted spaces. In fact, by using a discrete vector-valued local Calderón-Zygmund theory, which has recently been f…

Discrete harmonic analysis associated with Jacobi expansions I: the heat semigroup

Alberto Arenas, Óscar Ciaurri, Edgar Labarga

In this paper we commence the study of discrete harmonic analysis associated with Jacobi orthogonal polynomials of order . Particularly, we give the solution ,…
