| Abstract: | Given a sublinear operator T satisfying that ‖Tf‖Lp(ν) ≤ Cp-1‖f‖Lp(μ), for every 1 < p ≤ p0, with C independent of f and p, it has been recently proved that T : LlogL → M(φ), where M(φ) is the maximal Lorentz space with φ(t) = t(1 + log + t)-1. Also, if T satisfies that ‖Tf‖Lp(ν) ≤ Cp‖f‖Lp(μ), for every p ≥ p0, then T : Λ1(min(t - 1,1))∩L∞ → M(φ), where φ(t) =(1 + log + (1/t))-1. The purpose of this note, is to study embedding properties of the extrapolation spaces Llog L and M(φ) with respect toL1, and also embedding properties of Λ1(min(t - 1,1))∩L∞ and M(φ) with respect toL∞. We shall also extend these type of results to more general extrapolation theorems. |
