The graceful exit problem in string cosmology
Open accessAbstract
Abstract Isotropic string cosmology can be classified into duality related branches:one can be connected smoothyto an expanding Friedman-Robertson-Walker Universe, the describes accelerated inflation or contraction. We showthat, if the dilation potential has certain generic properties, the two branches can evolve smoothy into each other. We find,however, that just the effects of a potential do not allow for a graceful exit from accelerated inflation in the weak curvatureregime. We explain how conformal field theory techniques could be used to give a decisive answer on whether graceful exitfrom accelerated inflation is possible at all.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
