We introduce Lorentz spaces Lp(·),q(Rn) and Lp(·),q(·)(Rn) with variable exponents. We prove several basic properties of these spaces including embeddings and the identity Lp(·),p(·)(Rn)=Lp(·)(Rn) . We also show that these spaces arise through real interpolation between Lp(·)(Rn) and L∞(Rn) . Furthermore, we answer in a negative way the question posed in whether the Marcinkiewicz interpolation theorem holds in the frame of Lebesgue spaces with variable integrability.
