考虑由二次多项式定义的整数序列的项的本原因子。除了一些小的反例,当一个项有一个本原因子时,这个本原因子是唯一的。看起来有一个原始因子的项的数目有一个自然密度。我们讨论了两个启发式的参数,建议该密度的值,一个使用最近的进展多项式同余的根的分布。
We consider primitive divisors of terms of integer sequences defined by quadratic polynomials. Apart from some small counterexamples, when a term has a primitive divisor, that primitive divisor is unique. It seems likely that the number of terms with a primitive divisor has a natural density. We discuss two heuristic arguments to suggest a value for that density, one using recent advances made about the distribution of roots of polynomial congruences.
