摘要
研究了一类中立型变系数差分方程解的振动性,得到了其存在非振动解的充要条件及一些新的振动准则,其中包含一些“Sharp”准则.
The oscillation of the solutions of a type of nentral equation with variable cofficients is investigated.The necessary and sufficient conditions of existence of nonoscillatory solutions and several new oscillatory criteria for this equation are obtained.Some of these criteria are sharp.Many known theorems have been extended and improved.
