摘要 研究二阶差分方程xn+1=(xn xn-1)/(axn+bxn-1),n=0,1,2,…的奇点集和解{x n}∞n=-1的渐近性,其中a,b∈R,初始值x0,x-1∈R。并根据不同的情形,得到解的不同的收敛性。 The author studies the forbidden set and the convergence of solutions of the second-order difference equation xn-1=x^n xn-1/axn+bxn-1,n=0,1,2,…witha,b∈R and initial values x0,x-1 ∈ R.changing the condition of the equations, the difference conclusions of the convergence are drawn.
