摘要:

确定了一般映射的李雅普诺夫指数的标度行为附近的过渡到混沌通过III型不稳定性。一个临界指数$β$表示的缩放的李雅普诺夫指数作为一个函数,再注入概率和映射的非线性计算。发现临界指数在区间$0 < β< 1$上变化。这与早期的预测相反的李雅普诺夫指数的标度行为在III型不稳定性。

英文摘要:

The scaling behaviour of the Lyapunov exponent near the transition to chaos via type-III intermittency is determined for a generic map. A critical exponent $β$ expressing the scaling of the Lyapunov exponent as a function of both, the reinjection probability and the nonlinearity of the map is calculated. It is found that the critical exponent varies on the interval $0 < β< 1$. This contrasts with earlier predictions for the scaling behaviour of the Lyapunov exponent in type-III intermittency.
