获得具连续变量差分方程 x(t+τ)-x(t)+p(t)x(t-ττ)=0 的非振动解在脉冲扰动x(tk+τ)-x(tk)=6kx(tk),k∈N(1)下具有保持性的充分条件.
The authors obtain a sufficient condition for the persistence of nonoscillatory solutions of the difference equation with continuous variable x(t+τ)-x(t)+p(t)x(t-ττ)=0 under the impulsive perturbationsx(tk+τ)-x(tk)=6kx(tk),k∈N(1)
