摘要
In this paper, we study the asymptotic behavior of a nonoscillatory solutions of a differential equation:We obtain some sufficient conditions which ensure that all the nonoscillatory solutions of (1) tend either to infinity or to zero as t . Our results generalize and improve some of the results of Parhi (Acta. Math. Hung 42 (1983), 101-109.).
