摘要
研究一类二阶线性中立型有界时滞微分方程非振动解的存在性问题 ,建立非振动解存在的判定准则 .
Some criteria have been established for the existence of nonoscillation solution of second order linear neutral differential equations with bounded delay d 2dt 2[x(t)+px(t-τ)]+∑ni=1[Q i(t)x(t-σ i(t))-R i(t)x(t-θ i(t))]=0, where t≥t 0,n≥1 is an integar,p≠ ±1 ,τ>0,Q i(t),R i(t),σ i(t),θ i(t)∈C([t 0,∞),R +),i=1,2,…,n.
