具有多个时滞的非线性差分方程解的振动性

Oscillation of Nonlinear Differential Equations with Many Delays

讨论了具有多个时滞的非线性差方程 yn+ 1 -yn+∑ni =1qif (yn-ki) =0解的振动性 ,得到了方程解振动的一组充分条件 ,推广了文 [1 ][2 ]的一些结果 .

Oscillation criteria fornonlineardifferential equations with many delays:yn+ 1 -yn+∑n i =1 qif (yn-ki) =0 is established.Results obtained improves theories in the literature[1 ],[2 ].
