分段光滑连续映射中的边界碰撞共振分岔

Resonance near Border-Collision Bifurcations in Piecewise-Smooth, Continuous Maps

D. J. W. Simpson, J. D. Meiss

摘要:

由分段光滑连续映射的边界碰撞分叉形成的锁模区域(共振舌)通常表现出独特的香肠状几何形状,其夹点称为“收缩点”。在本文中,我们扩展了分段线性情况的展开[{ \em Nonlinearity},22(5):1123-1144,2009],以显示收缩点如何被非线性破坏。对于$N$维映射,我们得到了这个收缩点分支的余维3开折。我们表明,破坏的收缩点一般发生的鞍结分叉,平滑的香肠的一个边界,在其他边界留下一个扭结的曲线的创建。

英文摘要:

Mode-locking regions (resonance tongues) formed by border-collision bifurcations of piecewise-smooth, continuous maps commonly exhibit a distinctive sausage-like geometry with pinch points called "shrinking points". In this paper we extend our unfolding of the piecewise-linear case [{\em Nonlinearity}, 22(5):1123-1144, 2009] to show how shrinking points are destroyed by nonlinearity. We obtain a codimension-three unfolding of this shrinking point bifurcation for $N$-dimensional maps. We show that the destruction of the shrinking points generically occurs by the creation of a curve of saddle-node bifurcations that smooth one boundary of the sausage, leaving a kink in the other boundary.
