一类非线性变系数差分方程平衡点的全局吸引性

GLOBE ATTRACTIVITY OF A CLASS OF NONLINEAR DIFFERENCE EQUATIONS WITH VARIABLE COEFFICIENTS

本文利用相关的差分方程的全局吸引性研究了一类具时滞的非线性变系数差分方程的正平衡点=1的全局吸引性，获得了一个好的充分条件．

In this paper,the global attractivity of the positive equilibrium x= 1 of the following nonlinear de-lay difference equation with variable coefficients is inrestigated by using the corresponding related to a difference equation,A good sufficient condition is ab-tained.
