The cofinal property of the reflexive indecomposable Banach spaces

Spiros A. Argyros, Theocharis Raikoftsalis (2012)

Annales de l’institut Fourier

Similarity:

It is shown that every separable reflexive Banach space is a quotient of a reflexive hereditarily indecomposable space, which yields that every separable reflexive Banach is isomorphic to a subspace of a reflexive indecomposable space. Furthermore, every separable reflexive Banach space is a quotient of a reflexive complementably ℓ p -saturated space with 1 < p < ∞ and of a c 0 saturated space.

Some remarks on the space of differences of sublinear functions

Similarity:

Two properties concerning the space of differences of sublinear functions D(X) for a real Banach space X are proved. First, we show that for a real separable Banach space (X,‖·‖) there exists a countable family of seminorms such that D(X) becomes a Fréchet space. For X = ℝ^n this construction yields a norm such that D(ℝ^n) becomes a Banach space. Furthermore, we show that for a real Banach space with a smooth dual every sublinear Lipschitzian function can be expressed by the Fenchel...
