Victor **Torres-Perez***Chang's conjecture and the strong tree property*

Abstract:

We will show that a strong version of Chang's Conjecture implies the Strong
Tree Property for $\omega_2$, a weak version of Todorcevic's Square Principle
and the presaturation of the nonstationary ideals on $P_{\omega_2}(\lambda)$
for $\lambda\geq\omega_2$. This is a joint work with Liuzhen Wu.
