Query: 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.
