AbstractWe study when the spaces of Lorentz multipliers from Lp,t → Lp,s are distinct. Our main interest is the case when s < t, the Lorentz-improving multipliers. We prove, for example, that the space of multipliers which map Lp,t → Lp,s is different from those mapping Lp,t → Lp,s if either r = p or p′ and 1/s − 1/t ≠ 1/u − 1/v, or r ≠ p or p ...

Calderón Couples of Lorentz Spaces
Mathematische Nachrichten, 2001The authors receive some sufficient conditions under which pairs of Banach function lattices are Calderón couples. Applications of this results to the case of classical Lorentz spaces are considered.

[For part I, cf. ibid. 30, 116-122 (1987; Zbl 0633.53087).] A new theorem on the causality relation and its dependence on the acting group is given. Instructive examples are supplied.

Tent Spaces Based on the Lorentz Spaces
Mathematische Nachrichten, 1987The authors generalize the notion of tent spaces, introduced by R. Coifman, Y. Meyer, and E. Stein, by considering Lorentz spaces. This permits them to extend the atomic decomposition, obtained by Coifman, Meyer, and Stein, to the case of \(p>1\). The authors also show how Carleson measures and tent spaces can be used to simplify proofs of old results ...
