一类差分方程组解的性质研究

Study on the Properties of Solutions of a Class of Difference Equations

研究了差分方程组{xn+1=a+bx_(n-1)e^(-xn-yn) yn+1=c+dy_(n-1)e^(-xn-yn)系统正解的有界性和持久性,不变区间的存在性,渐近行为以及全局渐近稳定性.

In this paper,boundedness and persistence,the existence of the same interval,asymptotic behavior and global asymptotic stability of the positive solutions of a class of systems of difference equation {xn+1=a+bx_(n-1)e^(-xn-yn) yn+1=c+dy_(n-1)e^(-xn-yn) are studied.
