素数上的有理数生成子群的平均乘法阶

Average Multiplicative Order of Finitely Generated Subgroup of Rational Numbers Over Primes

Cihan Pehlivan

摘要:

给定一个由有理数$Γ$生成的乘法子群,在广义黎曼假设的条件下,给出了素数上的平均值的渐近公式,给出了约化群模$p$的阶的幂. Pomerance和Kurlberg在秩$1$的情况下考虑了这个问题。在$Γ$只包含正数的情况下,我们给出了所涉及的密度的欧拉积的显式表达式。最后我们用一些数值计算来作结论。

英文摘要:

Given a finitely generated multiplicative subgroup of rational numbers $Γ$, assuming the Generalized Riemann Hypothesis, we determine an asymptotic formula for average over prime numbers, powers of the order of the reduction group modulo $p$. The problem was considered in the case of rank $1$ by Pomerance and Kurlberg. In the case when $Γ$ contains only positive numbers, we give an explicit expression for the involved density in terms of an Euler product. We conclude with some numerical computations.
