E. Meletlidou et S. Ichtiaroglou, ON THE NONEXISTENCE OF AN ANALYTIC INTEGRAL OF MOTION IN PERIODICALLYPERTURBED ONE DEGREE-OF-FREEDOM HAMILTONIANS, Physics letters. A, 188(2), 1994, pp. 157-163
A criterion for proving non-integrability of one degree of freedom Ham
iltonians of the form H-0 + epsilonH-1, where H-0 is autonomous and ep
silonH-1 is a periodic time-dependent perturbation, is established. Ap
plications to two such systems are made and relations of the criterion
to the Melnikov subharmonic and homoclinic functions are found.
