多时标时滞方程的鸭式爆炸

Canard explosion in delayed equations with multiple timescales

Maciej Krupa, Jonathan D. Touboul

摘要:

我们分析了一维慢流形上延迟微分方程中鸭式爆炸问题。本文研究了具有时滞自耦合的van der Pol慢-快系统的动力学行为。在没有延迟的情况下,这个系统提供了鸭式爆炸的一个典型例子。我们表明,随着延迟的增加,一个家庭的“经典”鸭式爆炸结束Bogdanov-Takens分歧发生在S形的临界流形的折叠点。

英文摘要:

We analyze canard explosions in delayed differential equations with a one-dimensional slow manifold. This study is applied to explore the dynamics of the van der Pol slow-fast system with delayed self-coupling. In the absence of delays, this system provides a canonical example of a canard explosion. We show that as the delay is increased a family of `classical' canard explosions ends as a Bogdanov-Takens bifurcation occurs at the folds points of the S-shaped critical manifold.
