一类时滞差分方程的脉冲稳定性

On the Plus Stability of the Brood Time Lag Difference Equation

研究非线性时滞差分方程,获得了方程零解稳定的若干充分条件,指出方程的零解的稳定性是由脉冲扰动引起。本文方法也适用于方程。△x(n)=-ɑnx(n)+f(n,x(n-k))。

Conider nonlinear delay difference equation with impulsive perturbation s.Some sufficent conditions thent gurantee the zero solution of the equation be stable were obtained.The stab lity is aused by the impulsi-ue perturbations the method rnay be used for the equation△x(n)=-anx(n)+f(n,x(n-k)).
