Characterizing Lipschitz images of injective metric spaces

Judyta Bąk, Taras Banakh, Joanna Garbulińska-Węgrzyn +2

A metric space $X$ is {\em injective} if every non-expanding map $f : B \to X$ defined on a subspace $B$ of a metric space $A$ can be extended to a non-expanding map $f ˉ : A \to X$ .…

Gurarii operators are generic

Taras Banakh, Joanna Garbulińska-Wȩgrzyn

Answering a question of Garbulińska-Wȩgrzyn and Kubiś, we prove that Gurarii operators form a dense $G_{δ}$ -set in the space $B (G)$ of all nonexpansive operators on…
