Noncompact KK theory of gravity: stochastic treatment for a   nonperturbative inflaton field in a de Sitter expansion
  We study a stochastic formalism for a nonperturbative treatment of the inflaton field in the framework of a noncompact Kaluza-Klein (KK) theory during an inflationary (de Sitter) expansion, without the slow-roll approximation.
