1) binary recurrene sequence
二元线性递推数列
3) nonlinear recurrent sequence
非线性递推数列
1.
By using both of mathematical induction and method of undetermined coefficient,it is proved that some univariate equations of higher degree with integral coefficient have unique positive real solution,then the general terms of two nonlinear recurrent sequences are established,which generalize the results in Item 5,Paper One of 1989 National High School Mathematics Competition.
利用数学归纳法和待定系数法,通过证明某些整系数一元高次方程有且只有一个特殊的正实数解,得到两个非线性递推数列的通项公式,从而推广了1989年全国高中数学联赛第一试第五题的结果。
5) fractional linear recursive series
分式线性递推数列
1.
Application of matrix theory to solving the general formula of fractional linear recursive series;
矩阵理论在求分式线性递推数列通项公式中的应用
6) linear fraction recurrence
线性分式递推数列
补充资料:递归数列
递归数列 recursive sequence 一种用归纳方法给定的数列。例如,等比数列可以用归纳方法来定义,先定义第一项a1的值(a1≠0),对于以后的项,用递推公式an+1=qan(q≠0,n=1,2,…)给出定义。一般地,递归数列的前k项a1,a2,…,ak为已知数,从第k+1项起,由某一递推公式an+k=f(an,an+1,…,an+k-1)( n=1,2,…)所确定。k称为递归数列的阶数。例如 ,已知 a1=1,a2=1,其余各项由公式an+1=an+an-1(n=2,3,…)给定的数列是二阶递归数列。这是斐波那契数列,各项依次为 1,1,2,3,5,8,13,21,…,同样,由递归式an+1-an =an-an-1( a1,a2为已知,n=2,3,… ) 给定的数列,也是二阶递归数列,这是等差数列。 |
