Abstract

© 2018 World Scientific Publishing Company. We consider Hamiltonian systems with d degrees of freedom and a Hamiltonian of the form H = 1 2=i=1dp12 + V (q 1,...,qd), where V is a homogenous polynomial of degree n ≥ 3. We prove that such Hamiltonian systems with n odd or n = 4m, have a Darboux first integral if and only if they have a polynomial first integral.
