摘要
We consider a two-dimensional autonomous Hamiltonian system with heteroclinic contour under the action of a time-periodic perturbation. It is shown that the number of ultrasubharmonics in the perturbed system is estimated from below by a function proportional to the square of the logarithm of the perturbation parameter when this parameter tends to zero.
