Abstract

We show that if the Hardy–Littewood maximal operator M is bounded on a reflexive variable exponent space L p ( ) ( d ) , then for every q ( 1 , ) , the exponent p ( ) admits, for all sufficiently small θ > 0 , the representation 1 p ( x ) = θ q + 1 - θ r ( x ) , x d , such that the operator M is bounded on the variable Lebesgue space L r ( ) ( d ) . This result can be applied for transferring properties like compactness of linear operators from standard Lebesgue spaces to variable Lebesgue spaces by using interpolation techniques.
