Abstract:
We study spiral chaos in the classical Rössler and Arneodo –Coullet –Tresser systems. Special
attention is paid to the analysis of bifurcation curves that correspond to the appearance of
Shilnikov homoclinic loop of saddle-focus equilibrium states and, as a result, spiral chaos. To
visualize the results, we use numerical methods for constructing charts of the maximal Lyapunov
exponent and bifurcation diagrams obtained using the MatCont package.
Keywords:
Shilnikov bifurcation, spiral chaos, Lyapunov analysis.
