Query: Formalization of Forcing in Isabelle/ZF   We formalize the theory of forcing in the set theory framework of
Isabelle/ZF. Under the assumption of the existence of a countable transitive
model of ZFC, we construct a proper generic extension and show that the latter
also satisfies ZFC. In doing so, we remodularized Paulson's ZF-Constructibility
library.
