Webbfollowing result concerning (AR) will be crucial in constructing decaying slowly varying solutions of (IA). Theorem 3.1. Suppose that p(t) and q(t) are regularly varying functions of index 1 such that p(t) ˘q(t) as t!1. Then, the asymptotic system (AR) possesses decaying slowly varying solutions if and only if p(t) and q(t) are integrable Webbclass of slowly varying functions. The (seemingly) universal example of a slowly varying function in extreme value theory is a power of the natural log, e.g. λ ( ln ( x)) a for x > 0, λ ≥ 0, and a ≥ 0.
