Thus if we wish to show, e.g., that the continuum hypothesis is unprovable in ZFC we cannot just look for a transitive model ? that would satisfy 2. > N.. What is needed is a diff

Descriptive Set Theory images of closed sets) or are definable in a simple way. The main theme is that questions that are difficult to answer if asked for arbitrary sets of reals, become much easier when asked for sets that have a simple description. An example of that is the Cantor-Bendixson theorem (Theorem 14): Every

Forcing and Generic Models, that the continuum hypothesis is unprovable in ZFC we cannot just look for a transitive model ? that would satisfy 2. > N.. What is needed is a different way of constructing models of set theory. There are several possible approaches to this problem:
