On the sequence $\langle \text{pcf}^α(A): α\in \text{Ord} \rangle$

Published 2022-05-22Version 1

Modulo the existence of large cardinals, there is a model of set theory in which for some set $A$ of regular cardinals, the sequence $\langle \text{pcf}^\alpha(A): \alpha \in \text{Ord} \rangle$ is strictly increasing. The result answers a problem from [5].
