In mathematics, an orbit portrait is a combinatorial tool used in complex dynamics for understanding the behavior of one-complex dimensional quadratic maps. In simple words one can say that it is : * a list of external angles for which rays land on points of that orbit * graph showing above list ==Definition== Given a quadratic map : from the complex plane to itself : and a repelling or parabolic periodic orbit of , so that (where subscripts are taken 1 + modulo ), let be the set of angles whose corresponding external rays land at . Then the set is called the orbit portrait of the periodic orbit . All of the sets must have the same number of elements, which is called the valence of the portrait. 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「Orbit portrait」の詳細全文を読む スポンサード リンク
