Abstract: We (discuss ) introduce an exponential-type integrators for a class of Hamiltonian ordinary differential equations which allows to define uniform convergent schemes in the highly-oscillatory non-relativistic regime without any step-size restriction under the same setting on the initial data required for the integration of the corresponding nonlinear limit system.
