The consideration of dynamics of relativistic beams/particles is based on a variational approach to rational (in dynamical variables) approximations for equations of motions. It allows to control contributions from each scale of underlying multiscales and represents solutions via exact nonlinear eigenmode expansions. Our approach is based on methods providing possibility to work with well‐localized bases in phase space and good convergence properties of the corresponding expansions.
