A universal Banach space with a $K$ -unconditional basis

Taras Banakh, Joanna Garbulińska-Węgrzyn

For a constant $K \geq 1$ let $B_{K}$ be the class of pairs $(X, (e_{n})_{n \in ω})$ consisting of a Banach space $X$ and an unconditional Schauder basis $(\mathbf e_n)_…

The universal Banach space with a $K$ -suppression unconditional basis

Taras Banakh, Joanna Garbulińska-Węgrzyn

Using the technique of Fraïssé theory, for every constant $K \geq 1$ we consruct a universal object in the class of Banach spaces with normalized $K$ -suppression unconditional Schaud…

A universal operator on the Gurarii space

Joanna Garbulińska-Wȩgrzyn, Wiesław Kubiś

We construct a nonexpansive linear operator on the Gurarii space that "captures" all nonexpansive linear operators between separable Banach spaces. Some additional properties invol…
