Carl's inequality for quasi-Banach spaces
Carl's inequality relates several quantities from the geometry of Banach spaces. The classical proof relies heavily on the Hahn-Banach Theorem, which is known to fail for quasi-Banach spaces. We use a diff...

On binormality in non-separable Banach spaces
We study binormality, a separation property of the norm and weak topologies of a Banach space. We show that every Banach space which belongs to a P-class is binormal. We also show that the asplundness of a Bana...

On bases in Banach spaces
We investigate various kinds of bases in infinite dimensional Banach spaces Banach spaces and show that in a separable Banach space a Hamel basis cannot be analytic,whereas there are non-separable...

Non-universal families of separable Banach spaces
We prove that if C is a family of separable Banach spaces which is analytic universal for all separable Banach spaces, then there exists a separable Banach space separable Banach spac...

Compactness in quasi-Banach function spaces and applications to compact embeddings of Besov-type spaces
for the precompactness of sets in Banach function spaces to the setting of quasi-Banach function spaces. The second is to extend the criterion for the precompactness of sets in the Lebesgue spaces Lp(ℝn )...

Unital Banach algebras not isomorphic to Calkin algebras of separable Banach spaces
Recent developments in Banach space theory provided unexpected examples of unital Banach algebras that are isomorphic to Calkin algebras of Banach spaces, however no example of a unital Banach alg...

Complex Banach spaces with Valdivia dual unit ball
We study the classes of complex Banach spaces with Valdivia dual unit ball. We give complex analogues of several theorems of real spaces. Further we study relationship of these complex Banach spaces with t...

Genericity of Fréchet smooth spaces
If a separable Banach space X contains an isometric copy of every separable reflexive Fréchet smooth Banach space, then X contains an isometric copy of every separable Banach space. The same concl...
