摘要 研究了一类高阶有理差分方程xn=(pxn-s+xn-t)/(q+xn-t)n=0,1…解的有界性.其中{xn}为正实数数列,p,q,s,t>0,且初始解x-max{s,t},x1-max{s,t},…,x-1>0. In this paper,we investigate the boundedness of solution to a higher order rational difference equation xn=(pxn-s+xn-t)/(q+xn-t)n=0,1…with positive initial conditions where p,q,s,t are nonnegative integers.
