WebbParameter-dependent equilibrium solutions are analyzed as the parameter slowly varies through critical values corresponding to a bifurcation or to a jump phenomena. At these critical times, interior nonlinear transition layers are necessary. Webb15 aug. 1993 · The limit of validity of the slowly varying envelope approximation (SVEA) is derived as a function of the “bulk” velocity v of the radiating system, which reads lp ⪢λ (1− v/c ), lp being the radiation pulse length. This condition reduces to the usual SVEA in the limit v/c ⪡ 1, whereas it is sensibly relaxed in the relativistic limit.
In real analysis, a branch of mathematics, a slowly varying function is a function of a real variable whose behaviour at infinity is in some sense similar to the behaviour of a function converging at infinity. Similarly, a regularly varying function is a function of a real variable whose behaviour at infinity is similar to the … Visa mer Definition 1. A measurable function L : (0, +∞) → (0, +∞) is called slowly varying (at infinity) if for all a > 0, $${\displaystyle \lim _{x\to \infty }{\frac {L(ax)}{L(x)}}=1.}$$ Definition 2. Let L : … Visa mer • If L is a measurable function and has a limit $${\displaystyle \lim _{x\to \infty }L(x)=b\in (0,\infty ),}$$ then … Visa mer Regularly varying functions have some important properties: a partial list of them is reported below.

A multiple scale method is used to determine the amplitude and phase of the wave to the second order in the perturbation parameter.

WebbThe theory describes slowly varying wavetrains, with the oscillation locally in one of the normal modes of a waveguide of quite general structure. The governing equations need not be hyperbolic; the wavelike character of the solution may be imparted by the lateral boundary conditions in the waveguide (e. g. surface waves on water). devilbiss air power company pressure washerWebbSV class, the ƒclasses (see e.g. [3], or [5]), and the Beurling classes, the slowly varying one (see e.g. [5]) that contains the SV class, or the RV one (see [6]).
