Some Extensions of the Class of $$\mathscr {L}^p$$ -Spaces
Autor: M. J. Rivera
Publikováno v: Descriptive Topology and Functional Analysis II ISBN: 9783030173753
The \(\ell _p\) spaces play a central role in the classical theory of operators and finitely generated tensor norms. In this setting Lindenstrauss and Pelczyǹski (Stud Math 29: 275–326, 1968) introduced the class of the \(\mathscr {L}^p\)-spaces i
