摘要
讨论非齐次中立型微分差分方程d/dt[x(t)+Cx(t-τ)]+P(ι)x(t-σ)+f(ι)=0 t≥t_0的振动性,获得某些充分条件,并推广了某些齐次方程的结果.
Oscillation of the first order nonhomogeneous neutral differential difference equationsis discussed . Some Sufficient conditions are obtained and the result of oscillation of some homogeneous eolations is gener-alized.
