Query: Probabilistic and asymptotic methods with the Perron Frobenius's
  operator   We give a new global presentation of our results on the asymptotic behavior
of an iteration. This paper brings many improvements and corrections to our
previous preprints on the subject. Among the applications, we use new methods
to compute asymptotic results of PDE like Lorenz or Navier-Stokes equations.
New questions as the resonance are studied.
