On the three-space property for subprojective and superprojective Banach spaces
Manuel González, Javier Pello
We introduce the notion of subprojective and superprojective operators and we use them to prove a variation of the three-space property for subprojective and superprojective spaces…
Complemented subspaces of -sums of Banach spaces
Manuel González, Javier Pello
We study the complemented subspaces of the -sums of Banach spaces and introduced by Bellenot. As an application, we show that, under some conditions, a…
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 of
Manuel González, Javier Pello
We show that the Banach space is subprojective if is scattered and is subprojective.
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…
