  • 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(zhuǎn)化到整個平面上,給出旋轉(zhuǎn)數(shù)與hill方程的特征值的關(guān)系,并以此來度量漸近線性振子,再應(yīng)用pioncar - birkhoff扭轉(zhuǎn)定理得到周期碰撞解的存在性。
  • 百科解釋
In mathematics, the rotation number is an invariant of homeomorphisms of the circle. It was first defined by Henri Poincaré in 1885, in relation to the precession of the perihelion of a planetary orbit. Poincaré later proved a theorem characterizing the existence of periodic orbits in terms of rationality of the rotation number.
