Query: The Levy diffusion as an effect of sporadic randomness   The Levy diffusion processes are a form of non ordinary statistical mechanics
resting, however, on the conventional
  Markov property. As a consequence of this, their dynamic derivation is
possible provided that (i) a source of randomness is present in the
corresponding microscopic dynamics and (ii) that the consequent process of
memory erasure is properly taken into account by the theoretical treatment.
