Statistical mechanics of coupled map lattices. (English) Zbl 0791.60099
Kaneko, Kunihiko (ed.), Theory and applications of coupled map lattices. Chichester: John Wiley & Sons. Nonlinear Sci. Theory Appl. 169-189 (1993).
The paper is devoted to the coupled map lattices approach to the problem of the turbulence, i.e., of the spatiotemporal chaos in the behaviour of solutions of a spatially extended dynamical system. The coupled map lattice (CML) is a new class of dynamical systems with infinitely many degrees of freedom. The paper describes some classes of the CML with a short-range diffusive coupling on the one-dimensional lattice. The main tool for the proof of the existence of the spatiotemporal chaos is a modified version of the thermodynamic formalism for these CML. The phenomenon of the appearence of coherent structures from the chaotic state is discussed in connection with transition to ordered phases.
