de Sitter inflationary expansion from a noncompact KK theory: a   nonperturbative quantum (scalar) field formalism
  We develop a nonperturbative quantum scalar field formalism from a noncompact Kaluza-Klein (KK) theory using the induced-matter theory of gravity during inflation. We study the particular case of a de Sitter expansion for the universe.
