Oscillation of Solutions for a Class of Second-Order Nonlinear Variable Delay Difference Equation
摘要
Abstract
The oscillation of a class of second-order nonlinear neutral variable delay damped difference equation with positive and negative coefficients is discussed. By introducing parameter function and the generalized Riccati transformation, some new oscillation criteria for the equation are proposed. The results extend and improve the results given in literatures. An example is given to illustrate our main results.关键词
