Cembranos, Pilar2023-06-202023-06-2019970213-8743https://hdl.handle.net/20.500.14352/58203Since the birth of Banach space theory, it has been an important goal to know how are the subspaces of a given Banach space. An interesting part of that study has been focused in the search of criteria for a Banach space to have any of the classical sequence spaces as a subspace. Several deep results have revealed how the presence (or the absence) of such subspaces provides a very good insight in the internal structure of the Banach spaces involved.engAtribución-NoComercial 3.0 Españahttps://creativecommons.org/licenses/by-nc/3.0/es/journal articlehttps://matematicas.unex.es/~extracta/Extracta_Published_volumes.html#12-2open access517.982.2Spaces of vector valued functionsNormed linear spacesAnálisis funcional y teoría de operadores
