Models of set theory with definable ordinals

Models of set theory with definable ordinals A DO model (here also referred to a Paris model) is a model [InlineMediaObject not available: see fulltext.] of set theory all of whose ordinals are first order definable in [InlineMediaObject not available: see fulltext.]. Jeffrey Paris (1973) initiated the study of DO models and showed that (1) every consistent extension T of ZF has a DO model, and (2) for complete extensions T, T has a unique DO model up to isomorphism iff T proves V=OD. Here we provide a comprehensive treatment of Paris models. Our results include the following: http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archive for Mathematical Logic Springer Journals

Abstract

A DO model (here also referred to a Paris model) is a model [InlineMediaObject not available: see fulltext.] of set theory all of whose ordinals are first order definable in [InlineMediaObject not available: see fulltext.]. Jeffrey Paris (1973) initiated the study of DO models and showed that (1) every consistent extension T of ZF has a DO model, and (2) for complete extensions T, T has a unique DO model up to isomorphism iff T proves V=OD. Here we provide a comprehensive treatment of Paris models. Our results include the following:
