  12. 12. 1. Chaotic Evolution and Strange Attractors by David Ruelle: a thin well reviewed introductory booklet. 2. Dynamics: The Geometry of Behavior (Studies in Nonlinearity) by Abraham and Show. This is the best picture book for the introduction of nonlinear dynamics and chaos. 3. 非線形な世界 by 大野克嗣:大野さん独自の視点で描かれた素晴らしい本。特に脚注がw 4. カオスの中の秩序—乱流の理解へ向けて by P. ペルジェ: 最初これで勉強しました。良 書です。 5. 非線形動力学とカオス—トポロジカルなアプローチ (Frontiers in Science) An Experimental Approach to Nonlinear Dynamics and Chaos/Book and Disk (Studies in Nonlinearity) by Nicholas B. Tufillaro Tyler Abbot and Jeremiah Reilly : Java appletもついていて、好きな入門書です。 6. Chaos in Dynamical Systems by E.Ott. References: e.g.
