Abstract

Our main goal in this article is to study mixed norm estimates for the Cesàro means associated with Dunkl–Hermite expansions on ℝd. These expansions arise when one considers the Dunkl–Hermite operator (or Dunkl harmonic oscillator) Hκ:= −Δκ +|x|2, where Δκ stands for the Dunkl–Laplacian. It is shown that the desired mixed norm estimates are equivalent to vector-valued inequalities for a sequence of Cesàro means for Laguerre expansions with shifted parameter. In order to obtain such vector-valued inequalities, we develop an argument to extend these Laguerre operators for complex values of the parameters involved and apply a version of the three lines lemma. © 2017 American Mathematical Society.
