We first consider the Hamiltonian formulation of n=3 systems, in general, and show that all dynamical systems in ℝ3 are locally bi-Hamiltonian. An algorithm is introduced to obtain Poisson structures of a given dynamical system. The construction of the Poisson structures is based on solving an associated first order linear partial differential equations. We find the Poisson structures of a dynamical system recently given by Bender [J. Phys. A: Math. Theor. 40, F793 (2007)]. Secondly, we show that all dynamical systems in Rn are locally (n-1) -Hamiltonian. We give also an algorithm, similar to the case in ℝ3, to construct a rank two Poisson structure of dynamical systems in ℝn. We give a classification of the dynamical systems with respect to the invariant functions of the vector field X→ and show that all autonomous dynamical systems in ℝn are superintegrable. © 2009 American Institute of Physics.
