WebbThe class of regularly varying functions has been introduced in the 30s by Karamata, who defined the notion of slowly varying (SV) and regularly varying (RV) functions, … 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.

Since $t^0=1,$ this coincides with the definition in Wikipedia of slowly varying functions: a slowly varying function in which the relative differences in the tail is equal to zero: $$\lim_ {x\to \infty} \frac {f (tx) - f (x)} {f (x)}=0.$$
