A Baire-type theorem for cardinals
Published online by Cambridge University Press: 12 March 2014
Abstract
We shall prove the following theorem: If κ is an infinite cardinal and Γ: P(κ) → cf κ a partition of the power-set of κ then we can find a homogeneous ⊿-system of size κ such that the kernel of the ⊿-system is in the same partition class as all the members of the ⊿-system.
