Complex behavior in diffusively coupled systems with variable delay — •Jian Wang and Günter Radons — Institute of Physics, Chemnitz University of Technology, 09107 Chemnitz, Germany

In ubiquitous natural and laboratory situations the action of time delayed signals is a crucial ingredient to understand the dynamical behavior of these systems. A frequently encountered situation is that the length of the delay time changes with time. With the introduction of varying delay, a simple system can exhibit complicated behavior. In this study, we consider diffusively coupled extended systems, including coupled map lattice models and reaction diffusion equations, and investigate the system dynamic of such systems with variable delay. Lyapunov exponents and dynamical structure factors are calculated. Various classes of observed space-time structures are characterized and compared to the situation with constant delay.
