Abstract
The problem of existence of aglobal center manifold for a system of O.D.E. like
is considered. We give conditions onA(y), F(x, y), G(x, y) in order that a functionH: ℝm→ℝn, with the same smoothness asA(y), F(x, y), G(x, y), exists and is such that the manifoldC={(x,y)∈ℝn×ℝm∣x=H(y),y∈ℝm} is an invariant manifold for (*), and there exists ρ>0 such that any solution of (*) satisfying sup t∈ℝ∣x(t)∣ <ρ must belong toC. This is why we callC global center manifold. Applications are given to the problem of existence of heteroclinic orbits in singular systems.
