Noncompact Kaluza-Klein theory and inflationary cosmology: a complete formalism
arXiv:gr-qc/0405024 · doi:10.1016/j.physletb.2004.06.093
Abstract
A formalization of the recently introduced formalism for inflation is developed from noncompact Kaluza-Klein theory. In particular, the case for a single scalar field inflationary model is studied. We obtain that the scalar potential, which assume different representations in different frames, has a geometrical origin.
