Failures of square in Pmax extensions of Chang models

Paul B. Larson, Grigor Sargsyan

Published 2021-05-01Version 1

We show that the statements $\square(\omega_{3})$ and $\square(\omega_{4})$ both fail in the $\mathbb{P}_{\mathrm{max}}$ extension of a variation of the Chang model introduced by Sargsyan.
