Comments on multiple oscillatory solutions in systems with time-delay feedback
A complex Ginzburg-Landau equation subjected to local and global time-delay feedback terms is considered. In particular, multiple oscillatory solutions and their properties are studied. We present novel results regarding the disappearance of limit cycle solutions, derive analytical criteria...

description |
A complex Ginzburg-Landau equation subjected to local and global
time-delay feedback terms is considered. In particular, multiple
oscillatory solutions and their properties are studied. We present
novel results regarding the disappearance of limit cycle solutions,
derive analytical criteria for frequency degeneration, amplitude
degeneration, and frequency extrema. Furthermore, we discuss the
influence of the phase shift parameter and show analytically that
the stabilization of the steady state and the decay of all
oscillations (amplitude death) cannot happen for global feedback
only. Finally, we explain the onset of traveling wave
patterns close to the regime of amplitude death. |
