Abstract :There are two plausible strong axioms available on the market which both imply that there are $\aleph_2$ reals, Martin's Maximum and Woodin's (*). It is still unknown if these two are compatible with each other. This question leads to the formulation of a unifying strong axiom and also to studying apparently unrelated issues from descriptive inner model theory. This is joint work with Asperó, Claverie, Doebler, and Woodin.
