作为一个模型,以提供一个动手,基本的理解“涡动力学”,我们介绍了一个分段线性不可逆映射称为扭曲面包师映射。证明了具有复共轭特征值的双曲相斥周期点集和不具有复共轭特征值的双曲相斥周期点集在相空间中同时稠密。我们还表明,这两套equidistributed相对于归一化勒贝格措施,尽管在他们的李雅普诺夫指数的非均匀性。
As a model to provide a hands-on, elementary understanding of'vortex dynamics', we introduce a piecewise linear non-invertible map called a twisted baker map. We show that the set of hyperbolic repelling periodic points with complex conjugate eigenvalues and that without complex conjugate eigenvalues are simultaneously dense in the phase space. We also show that these two sets equidistribute with respect to the normalised Lebesgue measure, in spite of a non-uniformity in their Lyapunov exponents.
