RT Journal Article T1 A separation bound for non-Hamiltonian differential equations with proper first integrals A1 Gascón, Francisco G. A1 Peralta Salas, Daniel A1 Ruiz Sancho, Jesús María AB It is shown that when a dynamical system X0 with a proper set of global first integrals is perturbed, the phase space region accessible to the orbits of the perturbed vector field X0+Xp is bounded (we are assuming here that the time variable runs over a finite interval). A polynomial new bound is obtained for the separation between the solutions of X0 and X0+Xp. Perturbations near an equilibrium point of X0 are also considered.
