Abstract

In this paper we give sufficient conditions on a measurable function p:(0,)n[1,)p:(0,\infty)^n\rightarrow [1,\infty) in order that harmonic analysis operators (maximal operators, Riesz transforms, Littlewood--Paley functions and multipliers) associated with α\alpha-Laguerre polynomial expansions are bounded on the variable Lebesgue space Lp()((0,)n,μα)L^{p(\cdot)} ((0,\infty)^n, \mu_\alpha), where dμα(x)=2nj=1nxj2αj+1exj2Γ(αj+1)dxd\mu_\alpha (x)=2^n\prod_{j=1}^n \frac{x_j^{2\alpha_j+1} e^{-x_j^2}}{\Gamma(\alpha_j+1)} dx, being α=(α1,,αn)[0,)n\alpha=(\alpha_1, \dots, \alpha_n)\in [0,\infty)^n and x=(x1,,xn)(0,)nx=(x_1,\dots,x_n)\in (0,\infty)^n.
