The modal logic of forcing
What are the most general principles relating forceability and truth? As in Solovay's celebrated analysis of provability, this question and its answer are naturally formulated in modal logic. Specifically, define that a set theoretic assertion phi is *forceable* or *possible* if it holds in some forcing extension, and *necessary* if it holds in all forcing extensions. Under this forcing interpretation, the valid principles of forcing are exactly those in the modal theory known as S4.2. This is joint work with Benedikt Loewe.
