Intermittent dynamics

    Intermittency is the general dynamical phonemenon in which the dynamics switches, apparently randomly, between regular and chaotic behaviour. This work is concerned with the computation of the properties of intermittent systems using periodic orbits. In a nutshell, there are long but relatively stable periodic orbits that dominate the calculation, so it is important to order periodic orbit expansions by stability rather than length. A number of other techniques are also investigated in order to further accelerate convergence. Models include simple maps and the thermostatted Lorentz gas.
