Travelling fronts for correlated random walks. (English) Zbl 0802.60065
From the abstract: Scalar reaction diffusion equations describe Brownian motion and multiplication of particles. If Brownian motion is replaced by a correlated random walk, then one obtains nonlinear hyperbolic systems. In the special case of one hyperbolic equation and in the general case of a hyperbolic system the existence problem for travelling front solutions is studied in detail.
