摘要
利用里卡提方程方法为 Lane-Emdem-Fowler 和 Van der Pol 类方程建立了一些全局可解性标准。证明了两个振荡定理。所获得的结果被应用于埃姆登-福勒方程和范德尔波尔型方程。
Global Solvability and Oscillation Criteria for a Class of Second Order Nonlinear Ordinary Differential Equations, Containing Some Important Classical Models
The Riccati equation method is used to establish some global solvability criteria for a classes of Lane–Emdem–Fowler and Van der Pol type equations. Two oscillation theorems are proved. The results obtained are applied to the Emden–Fowler equation and to the Van der Pol type equation.
