Spatiotemporal Chaos


The term "chaos" denotes persistent irregular behavior of a deterministic system (that is, one in which externally applied noise can be neglected). Much of the work on chaos of the last 15 years has dealt with systems that could be represented by a small number of degrees of freedom, such as the logistic map u_(t+1) = ru_t(1 - u_t) or the famous Lorenz model involving nonlinear differential equations for three coupled dynamical variables. Remarkably, at least near enough to the threshold of chaos, continuous experimental systems such as stirred chemical reactors or flows in certain fluid cells can be represented by such models.
