κ-Ohio completeness

抄録

Generalizing the Ohio completeness property, we introduce the notion of κ-Ohio completeness. Although many results from a previous paper by the authors may easily be adapted for this new property, there are also some interesting differences. We provide several examples to illustrate this. We also have a consistency result; depending on the value of the cardinal d, the countable union of open and ω₁-Ohio complete subspaces may or may not be ω₁-Ohio complete.
