ON THE LYAPOUNOV CENTER THEOREM,
Abstract
Lyapounov proved there exists a 1-parameter family y periodic orbits for certain analytic Hamiltonian systems. The question of the differentiability of the resulting manifold of periodic selections was not considered. C. L. Siegel proved the analyticity of the resulting manifold. The results given in the present work settle the problem of existence and smoothness of the manifold for non-analytic systems. (Author)
