摘 要: 通过考查一类差分方程组,研究其正解的全局渐进稳定性,在参数满足不同的条件下,分别得出方程组的正解收敛于唯一正平衡点和方程组存在无界解的结论. This paper deals with the system of two difference equations and investigates its asymptotic behavior.While a certain condition prevails,every positive solution of the system converges to the unique positive equilibrium solution and the system possesses unbounded solutions respectively.
