An elementary embedding between two transitive models of set theory is cardinal preserving if its domain and target models have the same class of cardinals. The purpose of this note is to extend some ideas due to Caicedo and Woodin, leading to a proof that the critical point κ of a cardinal preserving embedding from the universe into an inner model is strongly compact in Vγ for some inaccessible cardinal γ > κ. In particular, we have the following consistency result:

Cardinal preserving elementary embeddings
Say that an elementary embedding j : N → M is cardinal preserving if CAR^M = CAR^N = CAR. We show that if PFA holds then there are no cardinal preserving elementary embeddings j : M → V. We alsoExpand
The Ultrapower Axiom
The inner model problem for supercompact cardinals, one of the central open problems in modern set theory, asks whether there is a canonical model of set theory with a supercompact cardinal. TheExpand
