空间扩展的循环优势石头剪刀布模型中的螺旋与异宿环

Spirals and heteroclinic cycles in a spatially extended Rock-Paper-Scissors model of cyclic dominance

C. M. Postlethwaite, A. M. Rucklidge

AI总结:

该研究针对空间扩展的循环优势石头剪刀布模型,通过数值计算行波的非线性色散关系,结合异宿分岔理论与二维模拟结果,预测了模型中螺旋波的整体结构与稳定性。

摘要:

循环优势石头剪刀布(Rock-Paper-Scissors)模型的空间扩展版本具有(一维中的)行波和(二维中的)螺旋行为。螺旋的远场表现得类似行波,而行波自身的波形会让人联想到异宿环。我们通过数值计算得到了行波波长与波速之间的非线性色散关系,再结合异宿分岔理论的见解以及二维模拟的更多数值结果,我们能够对二维循环优势模型中螺旋波的整体结构与稳定性作出预测。

英文摘要:

Spatially extended versions of the cyclic-dominance Rock-Paper-Scissors model have traveling wave (in one dimension) and spiral (in two dimensions) behavior. The far field of the spirals behave like traveling waves, which themselves have profiles reminiscent of heteroclinic cycles. We compute numerically a nonlinear dispersion relation between the wavelength and wavespeed of the traveling waves, and, together with insight from heteroclinic bifurcation theory and further numerical results from 2D simulations, we are able to make predictions about the overall structure and stability of spiral waves in 2D cyclic dominance models.
