Die Gewissheit unsicherer Zeitenonstruct symplectic maps for generic continuous Hamiltonian systems. We consider the generic Hamiltonian system (2.2) with small time-periodic perturbations. We shall discuss the main difficulties to construct mappings from Hamiltonian equations, and the shortcomings.

Perturbation Theory for Nearly Integrable Systems,perturbation of the integrable system. To study perturbed systems special theoretical methods, known as ., have been developed. They are based on the assumption that the solutions of a perturbed system are close to the corresponding solutions of the unperturbed (integrable) system, and one seeks the
