Starting from the assumption of the existence of a supercompact cardinal, a model is built in which for some such mu there are mu^{++} graphs on mu^+ that taken jointly are universal for the graphs on mu^+, while 2^{mu^+}>> mu^{++} . The paper also addresses the general problem of obtaining a framework for consistency results at the successor of a singular strong limit starting from the assumption that a supercompact cardinal kappa exists. The result on the existence of universal graphs is obtained as a specific application of a more general method.", "revisions": [ { "version": "v1", "updated": "2001-02-06T17:31:16.000Z" } ], "analyses": { "subjects": [ "03E35", "03E55", "03E75" ], "keywords": [ "universal graph", "singular cardinal", "strong limit singular mu", "supercompact cardinal kappa", "singular strong limit" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2001math......2043D" } } }
