<原報>カオスとフラクタルの「自己相似性」  [in Japanese] Chaos and Self-Similarity of Fractals  [in Japanese]

This article shows that the Self-Similarity in fractals is closely related to the structure of the chaos. The Euler sheme of dynamical system is considered, and its chaos features are presented by changing increment of t. Baker's map is used to show how Self-Similarity and Mixing are caused and figures under this map are compared with those of Poincare map. In the calculations of the Euler sheme, heteroclinic and homoclinic orbits are calculated and shown.
