种群动力学中的噪声诱导镇定

Noise induced stabilization in population dynamics

Matthew Parker, Alex Kamenev, Baruch Meerson

摘要:

我们研究了一个模型,其中强噪声在一个子种群创建一个亚稳态,否则不稳定的两个人口系统。诱导的亚稳态呈涡旋状,其持续时间随噪声强度呈指数增长。各种不同的标度关系,观察到的子种群噪声的相对强度。

英文摘要:

We investigate a model where strong noise in a sub-population creates a metastable state in an otherwise unstable two-population system. The induced metastable state is vortex-like, and its persistence time grows exponentially with the noise strength. A variety of distinct scaling relations are observed depending on the relative strength of the sub-population noises.
