Larger cardinals in Cichoń's diagram
Published online by Cambridge University Press: 12 March 2014
Abstract
We prove that in many situations it is consistent with ZFC that part of the invariants involved in Cichoń's diagram are equal to κ while the others are equal to λ, where κ < λ are both arbitrary regular uncountable cardinals. We extend some of these results to the case when λ is singular. We also show that cf is consistent with ZFC.
