Title:Non-integrability of first order resonances in Hamiltonian systems in
 three degrees of freedom




The normal forms of the Hamiltonian 1 : 2 : $\omega$ resonances to
degree three for $\omega = 1, 3, 4$ are studied for
integrability. We prove that these systems are non-integrable
except for the discrete values of the parameters which are well
known. We use the Ziglin-Morales-Ramis method based on the
differential Galois theory.
