非双曲不动点的2-周期轨道分支

Bifurcation of 2-periodic orbits from non-hyperbolic fixed points

Anna Cima, Armengol Gasull, Víctor Mañosa

摘要:

我们引入了具有非双曲不动点的一维映射族的2-圈性的概念,类似于具有弱焦点的平面向量场族的圈性。这个新概念对于研究从不动点分叉的2-周期轨道的个数是有用的。作为应用,我们研究了一些自然多项式映射族的2-圈性。

英文摘要:

We introduce the concept of 2-cyclicity for families of one-dimensional maps with a non-hyperbolic fixed point by analogy to the cyclicity for families of planar vector fields with a weak focus. This new concept is useful in order to study the number of 2-periodic orbits that can bifurcate from the fixed point. As an application we study the 2-cyclicity of some natural families of polynomial maps.
