设a,B ∈ Q ~* 是乘法独立的有理数.研究了素数集合p的自然密度δ(a,B),其中(a mod p)生成的子群F * p包含(B mod p).证明了在广义黎曼假设下,密度δ(a,B)存在且等于普适常数S = π p素数(1− p /(p3 −1))的正有理数倍.在关于a和B的较弱条件下,给出了δ(a,B)的一个显式值.这扩展并修正了Stephens(1976,J. Number Theory 8,313-332)的早期工作。我们还讨论了结果在二阶线性递归序列和δ(a,B)的确定的一些数值方面的背景下的相关性。
Abstract Let a ,  b ∈ Q * be rational numbers that are multiplicatively independent. We study the natural density δ ( a ,  b ) of the set of primes p for which the subgroup of F * p generated by ( a  mod  p ) contains ( b  mod  p ). It is shown that, under assumption of the generalized Riemann hypothesis, the density δ ( a ,  b ) exists and equals a positive rational multiple of the universal constant S =∏ p  prime  (1− p /( p 3 −1)). An explicit value of δ ( a ,  b ) is given under mild conditions on a and b . This extends and corrects earlier work of Stephens (1976, J. Number Theory 8 , 313–332). We also discuss the relevance of the result in the context of second order linear recurrent sequences and some numerical aspects of the determination of δ ( a ,  b ).
