摘要
采用半环分析法研究差分方程xn+1=1/(xn+xn-1)(n=0,1,…)解列{xn}∞n=-1的特性。在此基础上,给出在初始值满足x-1,x0∈(0,∞)情况下,其平衡点-x=2/2是全局渐近稳定的严格理论证明。
In this paper, we investigate the property of the positive solutions of the difference equation x(n+1)=1/(xn+x(n+1)) for n = 0, 1,… with semieycle analysis method and give the globally asymptotic stability of its unique equilibrium -↑x=√1/2 with any positive initial conditions.
