摘要: The role of symmetry is examined in systems displaying period-doubling instabilities. It found that symmetric orbits will not undergo period doubling except extraordinary cases. Such exceptional cases cannot occur a large class systems, including the sinusoidally driven damped pendulum and Lorenz equations.
