We now wish to begin to locally remove such resonances by trying, with the help of a canonical transformation, to go to a coordinate system which rotates with the resonant frequency.一窝小鸟 发表于 2025-3-29 07:27:45
Ling Li,Li Xu,Wu He,Yong Chen,Hong Cheno-dimensional surface. If we then consider the trajectory in phase space, we are interested primarily in its piercing points through this surface. This piercing can occur repeatedly in the same direction. If the motion of the trajectory is determined by the Hamiltonian equations, then the . + 1-th pCardioplegia 发表于 2025-3-29 14:01:39
Hind Benfenatki,Frédérique Biennierconverges (according to Newton’s procedure) and thus the invariant tori are not destroyed. The KAM theorem is valid for systems with two and more degrees of freedom. However, in the following, we shall deal exclusively with the case of two degrees of freedom.preeclampsia 发表于 2025-3-29 18:03:31
