一类非光滑超临界Hopf分支的扰动

Perturbation of a Nonsmooth Supercritical Hopf Bifurcation

Julie Leifeld

摘要:

物理模型的非光滑公式很常见,特别是在气候建模中。然而,在许多这些模型中,这种建模选择几乎没有理由,并且没有数学迹象表明非光滑系统中的结果行为与类似光滑系统中出现的行为一致。我探讨这个问题,通过分析一个特定的气候例子中的光滑和非光滑的Hopf分岔之间的关系。证明了在一个极限参数的微小变化下,非光滑分岔对光滑分岔的扰动。

英文摘要:

Nonsmooth formulations of physical models are common, particularly in climate modeling. However, in many of these models, there is little justification for this modeling choice, and no mathematical indication that the resulting behavior in the nonsmooth system is consistent with behavior that would arise in a similar smooth system. I explore this question by analyzing the relationship between a smooth and nonsmooth Hopf bifurcation in one particular climate example. I show that the nonsmooth bifurcation perturbs to the smooth bifurcation under small changes in a limiting parameter.
