Beginnings,even-dimensional space. If the forces are derived from a potential function, the equations of motion of the mechanical system have many special properties, most of which follow from the fact that the equations of motion can be written as a Hamiltonian system. The Hamiltonian formalism is the natural多余 发表于 2025-3-24 00:00:27

,Poincaré’s Continuation Method,mall parameter is zero, a periodic solution is obvious, and then by using the implicit function theorem it is shown that the periodic solution is in a family of periodic solutions. Poincaré used these ideas extensively, and they have become known as the .; see Poincaré (.).BIDE 发表于 2025-3-24 15:04:41
