Abstract:
For distributed evolutionary dynamical systems of the "reaction–diffusion" and "reaction–diffusion–advec-tion" types, we analyze the behavior of invariant numerical characteristics of the attractor as the diffusion coefficients decrease. We consider the phenomenon of multimode diffusion chaos, one of whose signatures is an increase in the Lyapunov dimensions of the attractor. For several examples, we perform broad numerical experiments illustrating this phenomenon.
