Interpolation of operators when the extreme spaces are $L^\infty$

Functional Analysis 2008-02-03 v1

Abstract

In this paper, equivalence between interpolation properties of linear operators and monotonicity conditions are studied, for a pair (X0,X1)(X_0,X_1) of rearrangement invariant quasi Banach spaces, when the extreme spaces of the interpolation are LL^\infty and a pair (A0,A1)(A_0,A_1) under some assumptions. Weak and restricted weak intermediate spaces fall in our context. Applications to classical Lorentz and Lorentz-Orlicz spaces are given.
