Examples
- First integral and integral invariants of relativistic birkhoff systems
系统的第一积分和积分不变量 - Establishment of the first integration and integral invariants of the relativistic birkhoff system
系统的第一积分与积分不变量的构造 - 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
对于周期解的存在性证明，我们引进新的坐标变换把右半平面上的碰撞问题转化到整个平面上，给出旋转数与hill方程的特征值的关系，并以此来度量渐近线性振子，再应用pioncar - birkhoff扭转定理得到周期碰撞解的存在性。 - 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
首先给出birkhoff中心、极小吸引中心、极小吸引子的刻划，然后给出对于公理a吸引子，非游荡集、极限集、 birkhoff中心、概率极限集、极小吸引中心、极小吸引子、 ruelle吸引子以及测度中心之间的一个层次关系。
