Asymptotic Behavior of Solutions of Even-Order Advanced Differential Equations

In this paper, we establish the qualitative behavior of the even-order advanced differential equation aυyκ−1υβ′+∑i=1jqiυgyηiυ=0, υ≥υ0. The results obtained are based on the Riccati transformation and the theory of comparison with first- and second-order equations. This new theorem complements and improves a number of results reported in the literature. Two examples are presented to demonstrate the main results
