Oscillation of second-order Emden-Fowler-type variable delay neutral differential equations
摘要
Abstract
The oscillatory behavior of a class of second-order Emden-Fowler-type nonlinear neutral variable delay functional differential equations is studied in this article.Using a couple generalized Riccati transformation and some necessary analytic techniques,we establish two new oscillation criteria for the equations,which improve and generalize some corresponding known results.关键词
