异宿圈的稳定性:一种新的研究方法

Stability of heteroclinic cycles: a new approach

Telmo Peixe, Alexandre A. Rodrigues

摘要:

本文针对对策论中的一个单参数模型,分析了六圈构成的三维流形中异宿网络中圈的稳定性.我们显示的渐近稳定性的内部平衡的存在兼容的参数值的范围内的网络,我们描述了一种渐近技术,以决定周期(网络内)是可见的数值。该技术包括减少相关的动态到一个合适的一维地图,所谓的\emph{projective map}。射影映射的不动点的稳定性决定了相应环的稳定性。这种新的渐近方法的描述是适用于更一般类型的网络,是潜在的有用的计算动力学。

英文摘要:

This paper analyses the stability of cycles within a heteroclinic network lying in a three-dimensional manifold formed by six cycles, for a one-parameter model developed in the context of game theory. We show the asymptotic stability of the network for a range of parameter values compatible with the existence of an interior equilibrium and we describe an asymptotic technique to decide which cycle (within the network) is visible in numerics. The technique consists of reducing the relevant dynamics to a suitable one-dimensional map, the so called \emph{projective map}. Stability of the fixed points of the projective map determines the stability of the associated cycles. The description of this new asymptotic approach is applicable to more general types of networks and is potentially useful in computational dynamics.
