DESCRIPTION:Several stochastic processes modelling molecular motors on a l
 inear track\, as Markov random walks on quasi 1D lattices and random walks
  with non exponential waiting times\, share a common regenerative structur
 e and their mathematical investigation can be reduced to the study of a ti
 me changed sum of i.i.d. random vectors. \n\nFrom the analysis of this abs
 tract common structure\, one can derive information on the asymptotic velo
 city\, Gaussian fluctuations and large fluctuations for the original stoch
 astic process. \n\nIn this talk I will present the above results and\, con
 cerning large fluctuations\, I will discuss Gallavotti–Cohen–type symm
 etries for this model.\nThis is a joint work with Alessandra Faggionato (L
 a Sapienza\, Rome).
