摘要
讨论了由分式线性递推式x_(n+1)=(ax_n+b)/(cx_n+d)(其中a, b, c, d, x_1;∈C,且.c≠0,ad-bc≠0)确定的数列{x_n}的存在性,得到了以a, b, c,d,x_1直接表示的一个充分必要条件。
Where a, b, c, d, x_1,∈C and c ≠0, ad - bc ≠0, existence concerning Sequence of number for fractional linear recurrence formula x_(n + 1) =(ax_n. + b)/(cx_n + d) is studied, a necessary and suffcient condition of direct indication as a, b, c, d, x_1 is obtained.
