Banach space theory, a cornerstone of functional analysis, investigates complete normed vector spaces and the continuous linear operators acting between them. Within this framework, operator ideals ...

Banach space theory is a central branch of modern functional analysis concerned with the properties of complete normed vector spaces. This area of mathematics encompasses the study of geometric ...

We construct an infinite-dimensional superreflexive real Banach space which does not admit complex structure and consequently is not isomorphic to the Cartesian square of any Banach space. We also ...
