Abstract
We establish asymptotic representations as t → ω (ω ≤ + ∞) of a class of monotone solutions of the second-order differential equation y″ = f(t, y, y′), where f:[a,ω[× Δ Y0 × Δ Y1 is a continuous function asymptotically close on the considered class of solutions to a function of the form ±p(t)φ 0(y)φ 1(y′) with functions φ 0 and φ 1 regularly varying as y → Y 0 and y′ → Y 1. Here Δ Yi , i ∈ {0, 1}, is a one-sided neighborhood of Y i , and Y i is either zero or ±∞.
