有理分函数

Rational partition function

有理分函数可以简单地定义为二元多项式的商,由函数本身所决定的,这二元多项式不是唯一的,由于可能把分子与分母都乘以同一非零数的缘故,理论上是不能认为相同的。事实上,它们的自变量区间是不相同的,不包含在第一个函数的自变量变区中,就包含在第二函数的自变量变区中,因此就要要对有理分函数的定义加以某些限制。

The rational function can be simply defined as binary polynomial,decided by the function itself,but it is not unique,because may put the numerator and denominator multiplied by the same non-zero reason,the theory is not the same.In fact,these intervals are not the same,included in the first argument of function area,or included in the second argument function region,therefore it is necessary to define to rational functions to certain restrictions.
