Resumen de On Integrable Natural Hamiltonian Systems on the Suspensions of Toric Automorphism

• We correct a mistake in Liu and Zhang (Qual Theory Dyn Syst 9(1–2):301–318, 2010). Namely, we show that Liu and Zhang [Qual Theory Dyn Syst 9(1–2):301–318, 2010, Theorem 1.1(c)] is wrong for the energy levels that are not greater than the maximum of the potential energy, and formulate and prove the correct statement.
