Web25 Jun 2024 · Class forcing in its rightful setting. This is a talk at the Kurt Godel Research Seminar, University of Vienna, June 25, 2024 (virtual). The use of class forcing in set theoretic constructions goes back to the proof Easton's Theorem that GCH G C H can fail at all regular cardinals. Class forcing extensions are ubiquitous in modern set theory ... Webmodel theory, set theory and order theory. Then we introduce the concept of a forcing poset and a generic lter over a poset, and explain how to construct the generic extension of a model. After verifying that generic extensions are models of set theory, we use the technique to verify both directions of the independence of the continuum hypothesis.
