Spatial structure and stability based on random walks

  • Hiroaki Hara


A general expression for a recursion formula which describes a random walk with coupled modes is given. In this system, the random walker is specified by the jumping probabilities P+ and P which depend on the modes. The transition probability between the modes is expressed by a jumping probabilityR(ij) (orrij). With the aid of this recursion formula, spatial structures of the steady state of a coupled random walk are studied. By introducing a Liapunov function and entropy, it is shown that the stability condition for the present system can be expressed as the principle of the extremum entropy production.
