On variable exponent Lebesgue spaces of entire analytic functions

Abstract

In this article we introduce the variable Lebesgue spaces of entire analytic functions Lp(⋅)K. A maximal inequality of Jawerth is generalized to our context and inequalities of Plancherel–Polya–Nikolʼskij type are obtained. We calculate the dual of the space Lp(⋅)K when the function χK is an Lp(⋅)-Fourier multiplier and a number of consequences of this result (on sequence space representations) is given. Finally, a Fourier multiplier theorem by Triebel is extended to the setting of the variable Lebesgue spaces.
