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.
