The fixed point property in a Banach space isomorphic to $c_{0}$

Costas Poulios

We consider a Banach space, which comes naturally from c0 and it appears in the literature, and we prove that this space has the fixed point property for non-expansive mappings.

Non-separable tree-like Banach spaces and Rosenthal's $ℓ_{1}$ -theorem

Costas Poulios

We introduce and investigate a class of non-separable tree-like Banach spaces. As a consequence, we prove that we can not achieve a satisfactory extension of Rosenthal's $ℓ_{1}$ -t…
