In the mathematical discipline known as complex dynamics, the Herman ring is a Fatou component.〔John Milnor, (''Dynamics in one complex variable'' ): Third Edition, Annals of Mathematics Studies, 160, Princeton Univ. Press, Princeton, NJ, 2006.〕 where the rational function is conformally conjugate to an irrational rotation of the standard annulus. ==Formal definition== Namely if ''ƒ'' possesses a Herman ring ''U'' with period ''p'', then there exists a conformal mapping : and an irrational number , such that : So the dynamics on the Herman ring is simple. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Herman ring」の詳細全文を読む スポンサード リンク
