A note on the geometry of certain classes of linear operators
Diogo Diniz, Anselmo Raposo
In this note we introduce a new technique to answer an issue posed in [7] concerning geometric properties of the set of non-surjective linear operators. We also extend and improve…
Spaceability of the sets of surjective and injective operators between sequence spaces
Diogo Diniz, Vinícius Fávaro, Daniel Pellegrino +1
We investigate algebraic structures within sets of surjective and injective linear operators between sequence spaces, completing results of Aron et al.
A note on lineability
G. Botelho, D. Diniz, D. Pellegrino +1
In this note we answer a question concerning lineability of the set of non-absolutely summing operators.
Lineability of the set of bounded linear non-absolutely summing operators
G. Botelho, D. Diniz, D. Pellegrino
In this note we solve, except for extremely pathological cases, a question posed by Puglisi and Seoane-Sepulveda on the lineability of the set of bounded non-absolutely summing lin…
