ASPERÓ–MOTA ITERATION AND THE SIZE OF THE CONTINUUM
Published online by Cambridge University Press: 02 May 2022
Abstract
In this paper we build an Asperó–Mota iteration of length $\omega _2$ that adds a family of
$\aleph _2$ many club subsets of
$\omega _1$ which cannot be diagonalized while preserving
$\aleph _2$. This result discloses a technical limitation of some types of Asperó–Mota iterations.
