In the mathematical discipline of set theory, forcing is a technique for proving consistency and independence results. It was first used by Paul Cohen in 1963, to prove the independence of the axiom of choice and the continuum hypothesis from Zermelo–Fraenkel set theory. Forcing has been considerably … See more A forcing poset is an ordered triple, $${\displaystyle (\mathbb {P} ,\leq ,\mathbf {1} )}$$, where $${\displaystyle \leq }$$ is a preorder on $${\displaystyle \mathbb {P} }$$ that is atomless, meaning that it satisfies the … See more Given a generic filter $${\displaystyle G\subseteq \mathbb {P} }$$, one proceeds as follows.
