讨论了不规则散射区域中散射奇异集的性质。我们展示了如何使用集合的符号组织来确定分形维数和标度函数。这就得到了有界轨道的李雅普诺夫指数分布的信息。所研究的具体模型是一个粒子在平面上的运动,被以等边三角形四角为中心的三个圆盘弹性反射。
We discuss properties of the set of scattering singularities in regions of irregular scattering. We show how a symbolic organisation of the set can be used to determine the fractal dimension and the scaling function. This yields information on the distribution of Lyapunov exponents of bounded orbits. The specific model studied is the motion of a particle in a plane, elastically reflected by three circular discs centred on the corners of an equilateral triangle.
