From persistent random walks to the telegraph noise

Probability 2008-10-06 v1

Abstract

We study a family of memory-based persistent random walks and we prove weak convergences after space-time rescaling. The limit processes are not only Brownian motions with drift. We have obtained a continuous but non-Markov process (Zt)(Z_t) which can be easely expressed in terms of a counting process (Nt)(N_t). In a particular case the counting process is a Poisson process, and (Zt)(Z_t) permits to represent the solution of the telegraph equation. We study in detail the Markov process ((Zt,Nt);t0)((Z_t,N_t); t\ge 0).
