摘要
研究了具有负中立型项的二阶自共轭非线性差分方程的渐近性.利用广义的离散Riccati变换和函数序列的构造,给出了3种情形下差分方程非振动解的渐近性.
The asymptotic behaviors for second-order nonlinear difference equation with negative neutral term were discussed by using the generous discrete Riccati transformation and the construction of sequence of functions, so did the nonoscilational solutions of the equation in three conditions.
