一类非线性中立型差分方程的等价定理

Equivaient Theorem for Oscillation of Nonlinear Neutral Difference Equations

首先建立了下列两差分方程振动性的等价定理，然后给出方程（*）的一些特殊情形的振动性的充分条件．

First the equivalent theorem of the oscillation of the following two difference equations is established.Then, the sufficient conditions for oscillation of some specific types of Eq.(* ) are obtained.
