WebbThe theory of regular variation was initiated by Karamata in 1930 (see [BGT]) for continuous functions, but began to achieve its modern form only in 1949 in the work of Korevaar et al. [KvAEdB], where it is extended to (Lebesgue) measurable functions. It may also be developed for functions which have the property of Baire (brie°y, Baire functions).

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.
