The two-disjoint-copies property for compact spaces, homogeneity and connection with $C_{p}$ -theory

Jerzy Kąkol, Ondřej Kurka, Wiesław Śliwa

A Tychonoff space $X$ has the two-disjoint-copies property (2DCP) if there exists a sequence $(K_{n})_{n \in ω}$ of non-empty compact subsets of $X$ such that each $K_{n}$ contains two d…

Borel complexity of isometry classes of $C (K)$ spaces with countable compacta

Marek Cúth, Martin Doležal, Ondřej Kurka +1

For every countable compact space $K$ , we determine the exact Borel complexity of the isometry class of the Banach space $C (K)$ . As a byproduct, we also determine the pre…
