摘要：An estimate on the number of distinct relative periodic orbits around a stable relative equilibrium in a Hamiltonian system with continuous symmetry is given. This result constitutes a generalization to the Hamiltonian symmetric framework of a classical result by Weinstein and Mor on the existence of periodic orbits in the energy levels surrounding a stable equilibrium. The estimate obtained is very preci in the n that it provides a lower bound for the number of relative periodic orbits at each pre京中有善口技者原文

Moreover, it is easily computable in particular examples. It is interesting to e how, in our result, the existence of non-trivial relative periodic orbits requires (generic) 自强不息的近义词
