群速度接近对流-绝对不稳定性的亚临界和超临界分叉模式的噪声敏感性
Noise sensitivity of sub- and supercritically bifurcating patterns with group velocities close to the convective-absolute instability
摘要:
小的加性噪声对结构形成的影响附近的一个前锋和附近的一个倒置的分叉所描述的一个三次和五次Ginzburg朗道振幅方程,分别,数值研究群速度在附近的对流绝对不稳定的确定性的前动力学将清空系统。
英文摘要:
The influence of small additive noise on structure formation near a forwards and near an inverted bifurcation as described by a cubic and quintic Ginzburg Landau amplitude equation, respectively, is studied numerically for group velocities in the vicinity of the convective-absolute instability where the deterministic front dynamics would empty the system.
