On asymptotic description of passage through a resonance in quasi-linear Hamiltonian systems
Anatoly Neishtadt, Tan Su
We consider a quasi-linear Hamiltonian system with one and a half degrees of freedom. The Hamiltonian of this system differs by a small, , perturbing term from the…
Estimates of some integrals related to variations of smooth functions
Anatoly Neishtadt
Estimates of some integrals related to variations of smooth functions are presented.
On phenomenon of scattering on resonances associated with discretisation of systems with fast rotating phase
Anatoly Neishtadt, Tan Su
Numerical integration of ODEs by standard numerical methods reduces a continuous time problems to discrete time problems. Discrete time problems have intrinsic properties that are…
Directed transport in a classical lattice with a high-frequency driving
A. P. Itin, A. I. Neishtadt
We analyze the dynamics of a classical particle in a spatially periodic potential under the influence of a periodic in time uniform force. It was shown in [S.Flach, O.Yevtushenko,…
