关于Lyness方程的周期性证明的一种算法

A DEMONSTRATION METHOD ABOUT PERIODICITY OF LYNESS EQUATION

考虑Lyness方程的周期性 ,利用结式消去法 ,通过整序 ,在参数为负和复的情形得到了方程周期性结论 ,推广了文有关论著的结果 .

By using resultant elimination method, and analyzing coefficient of resultant, the periodicity of Lyness equation is considered. Some conclusions of periodicity of Lyness equation with negative or complex number coefficient are abtained.
