Abstract

Assume that L^p,q, L^p1, ^q1,..., LL^pn, ^qn are Lorentz spaces. This article studies the question: what is the size of the set We prove the following dichotomy: either E =L^p1, ^q1× ... × L^pn, ^qn or E is σ-porous in L^p1, ^q1× ... × L^pn, ^qn, provided 1/p ≠ 1/p₁ + ... + 1/p_n. In general case we obtain that either E = L^p1, ^q1× ... × L^pn, ^qn or E is meager. This is a generalization of the results for classical L^p spaces.
