摘要
研究了差分系统xn+1=1+yn/yn-m,yn+1=1+xn/xn-m正解的持久性及其全局渐近行为,其中m为正整数,得到一些新的结果。
Persistence and global asymptotic behavior of the positive soluitions of system of difference equations xn+1=A+yn/yn-m,yn+1=A+xn/xn-m are discussed ,where m is a positive integer,A and B are positive. Some new results' are obtained.
