摘要
研究三阶有理差分方程x_(n+1)=ax_(n-1)+x_(n-1)x_n/bx_(n-2)+cx_n,n=0,1,2,...的奇点集和解{x_n}_(n=-2)~∞的渐近性,其中a,b,c∈R,初始值x_(-2),x_(-1),x_0∈R.由a,b,c的取值的不同,而得到解的不同的渐近性.
We study the forbidden set and asymptotic behaviour of solutions of the threeorder difference equation x_(n+1)=ax_(n-1)+x_(n-1)x_n/bx_(n-2)+cx_n,n=0,1,2,... With a,b,c ∈ R and initial valuas x_(-2),x_(-1),x_0∈R.By the value of a,b,c is different,and obtain the different asymptotic behavior of solutions.
