On Open-Open Games of Uncountable Length
The aim of this paper is to investigate the open-open game of uncountable length. We introduce a cardinal number 𝜇(𝑋), which says how long the Player I has to play to ensure a victory. It is proved that 𝑐(𝑋)≤𝜇(𝑋)≤𝑐(𝑋)+. We also introduce the class 𝒞𝜅 of topological spaces that can be represented as...
