摘要
考虑一阶线性微分差分方程x′(t)+(1)其中 h_i.我们建立了方程(1)的解振动的充分条件,也讨论了它的非振动解的渐近性质。所得结果改进并推广了Ladas 等人[8,10]的一些结果。
A Kind of linear differential-difference equation of first order is considered in the paper.Some sufficient conditions for the oscillation of the solution are given.We also discuss the asymptotic properties of oon-oscillatic solutions.
