摘要
本文得到具有正负周期系数的差分方程振动的一个充分必要条件 ,并利用此充要条件获得了一个线性化振动性结果 .
It is proved that in certain conditions, oscillation of difference equation with positive and negative periodic coefficients and existence of positive roots of its characteristic equation are equivalent. This result is also applied to obtain a linearized oscillation result.
