解釋
伯克霍夫-
First, we describe the birkhoff center, the minimal attractive center and the minimal attractor. second, we give relationships among the attractor of axiom a, the non - wandering set, the limit set, the birkhoff center, the probability limit set, the minimal attractive center, the minimal attractor, the ruelle attractor and the measure center
首先給出birkhoff中心、極小吸引中心、極小吸引子的刻劃，然後給出對于公理a吸引子，非游蕩集、極限集、 birkhoff中心、概率極限集、極小吸引中心、極小吸引子、 ruelle吸引子以及測度中心之間的一個層次關系。 -
In order to prove the existence of the periodic boucing solutions, firstly we will introduce a new coordinate transformation, transform the system from right half plane to the whole plane. and give the relation of the eigenvalues of hill ' s equation and the rotation numbers, using this approach and pioncar - birkhoff twist theorem, we proved the existence of the periodic bouncing solutions for asymptotical linear oscillator
對于周期解的存在性證明，我們引進新的坐標變換把右半平面上的碰撞問題轉化到整個平面上，給出旋轉數與hill方程的特徵值的關系，並以此來度量漸近線性振子，再應用pioncar - birkhoff扭轉定理得到周期碰撞解的存在性。 -
