Borel complexity of isometry classes of spaces with countable compacta
Marek Cúth, Martin Doležal, Ondřej Kurka +1
For every countable compact space , we determine the exact Borel complexity of the isometry class of the Banach space . As a byproduct, we also determine the pre…

Isomorphisms between spaces of Lipschitz functions
Leandro Candido, Marek Cúth, Michal Doucha
We develop tools for proving isomorphisms of normed spaces of Lipschitz functions over various doubling metric spaces and Banach spaces. In particular, we show that $\operatorname{…
