摘要
考虑二阶拟线性微分方程 :( |y′|α -1y′)′+q(t) |y|α -1y=0 ,获得了在 q(t)振动的条件下该方程非振动的一些充分 (必要 )条件 。
Consider the second order quasilinear differential equation:(｜y′｜ α-1 y′)′+q(t)｜y｜ α-1 y=0.Sufficient conditions for nonoscillation of this equation are obtained under q(t) being oscillate.Our results improve and generalize some known results.
