Title: The strength of $\text{PFA}(\aleph_2)$ plus a precipitous Ideal on $\omega_1$

Abstract:

We will present an argument for extracting strength from the above mentioned hypothesis building on a work of Claverie and Schindler. We will give a short overview of the inner model theory used with a focus on showcasing the core ideas underpinning our methods. We will discuss limitations of the argument and ideas on how to overcome them.
