Query: Nonlinear Beam Dynamics and Effects of Wigglers   We present the applications of variational--wavelet approach for the
analytical/numerical treatment of the effects of insertion devices on beam
dynamics. We investigate the dynamical models which have polynomial
nonlinearities and variable coefficients. We construct the corresponding
wavelet representation for wigglers and undulator magnets.
