Research Abstract

カオスや大自由度系を含む力学系の大域的構造とその分岐を幾何的方法, 位相的方法, 複素解析的方法, さらには応用に現れる具体的な数理モデルの解析などの様々な側面から研究して多くの成果を得た.特に本研究では, 位相的方法を, 精度保証付き数値計算に基づく計算的方法と組み合わせて力学系の大域的構造と分岐についての数学的に厳密な計算機支援解析の方法を開拓し, 特異分岐構造の存在, カオス的振舞いを示す記号力学系の埋め込み, 双曲性の検証などのいくつかの重要な問題を解決した.これは力学系の多様な振舞いを解析するための1つの有用な方法として今後, 発展していく可能性があると期待される.
