The two-dimensional Lorentz space $L^{p,q}_2$ is defined as a special case from the two-dimensional space $\Lambda^p_2(w)$ just as was done in the classical dimension one. The normability and duality of the space $L^{p,q}_2$ are discussed.
Ключевые слова и фразы:Lorentz space, normability, duality, non-increasing rearrangement.
