注意代数(algebra)指的就是有双线性积的向量空间. 1. 群作用 教科书讲群大多都从变换群或置换群讲起,作用在有限集合 X 上的对称群 S(X) 就是把 X 中的元 x 打乱重组的所有操作,即 X\rightarrow X 的双射(一一对应,不能丢失或添加某个元)的集合. 注意“不对某些元操作”在这里也被视为一种操作,...

By using action variational principle,the transfer symplectic matrix for the discrete integral of the Hamiltonian canonical equation was given. Then the Lie algebra corresponding to the Hamiltonian canonical equation was given. When the time step tends to zero,that the symplectic group of the transfer...
