摘要
we revisit the Lorentz spaces L(p, q) for p %26gt; 1, q %26gt; 0 defined by G. G. Lorentz in the nineteen fifties and we show how the atomic decomposition of the spaces L (p, 1) obtained by De Souza in 2010 can be used to characterize the multiplication and composition operators on these spaces. These characterizations, though obtained from a completely different perspective, confirm the various results obtained by S. C. Arora, G. Datt and S. Verma in different variants of the Lorentz Spaces.
