我们提出了两个有效的测试,确定一个给定的多项式是分圆的,或者是分圆的产品。第一种方法利用了分圆多项式的所有根都是单位根的事实,第二种方法利用了分圆多项式的次数是φ(n)的值的事实,对于某些n。我们也可以找到任何多项式的分圆因子。
We present two efficient tests that determine if a given polynomial is cyclotomic, or is a product of cyclotomics. The first method uses the fact that all the roots of a cyclotomic polynomial are roots of unity, and the second the fact that the degree of a cyclotomic polynomial is a value of φ(n), for some n. We can also find the cyclotomic factors of any polynomial.
