Slowly varying

Webb8 nov. 2024 · then L is a slowly varying function. For any β ∈ R, the function L(x) = log β x is slowly varying. The function L(x) = x is not slowly varying, nor is L(x) = x β for any real β ≠ 0. However, these functions are regularly varying. See also. Analytic number theory; Hardy–Littlewood tauberian theorem and its treatment by Karamata; Notes WebbThe fundamental theorem for slowly varying functions of a real variable is Karamata's representation theorem: /is slowly varying if and only if f(x) = c(x) expif* ô(t)/tdt), where c(x) — c as x —* + <», c > 0, and S(x) is a *o continuous function tending to 0 as x — °° (see [1]).

The slowly varying envelope approximation revisited

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. WebbIn a first step, no torque is applied to the particle, so that its motion is described by a Hamiltonian with slowly varying parameters. We show that the torque applied to the satellite, as measured by ∈ s = j s / ( n s J s) induces an distortion of the phase space which is entirely described by an asymmetry coefficient α = ∈ s /μ, where ...
