The perturbation classes problem for subprojective and superprojective Banach spaces
Manuel González, Javier Pello, Margot Salas-Brown
We show that the perturbation class for the upper semi-Fredholm operators between two Banach spaces X and Y coincides with the strictly singular operators when X is subprojective a…
On subprojectivity and superprojectivity of Banach spaces
Elói M. Galego, Manuel González, Javier Pello
We obtain some results for and further examples of subprojective and superprojective Banach spaces. We also give several conditions providing examples of non-reflexive superproject…
Banach spaces of universal disposition
Antonio Aviles, Felix Cabello, Jesus M. F. Castillo +2
In this paper we present a method to obtain Banach spaces of universal and almost-universal disposition with respect to a given class of normed spaces. The method pro…
