WebbWhen the exciting frequency is relatively small, by regarding the whole exciting term as a slow-varying parameter, the original system can be transformed into a generalized autonomous system. The phase space can be divided into three regions by the nonsmooth boundaries, in which the trajectory is governed by three different subsystems, respectively.

Webb5 mars 2024 · By “slowly varying” we mean here that in any small region the wave function is well approximated by a plane wave, and that the wavelength only changes over distances long compared with a wavelength. We’re also assuming for the moment that the particle has positive kinetic energy in the region.

WebbFor a slowly varying function in its additive version, K in (3) is zero. A bounded f satisfying (3), where K cannot be taken as zero, is f(x) = (-1) x]. An example of an unbounded f of this kind can be obtained by adding the additive version of any unbounded slowly varying function; e.g., f(x) = (-1)[x] + logx.
