欧拉函数的小值与黎曼假设

Small values of the Euler function and the Riemann hypothesis

Jean-Louis Nicolas

摘要:

设$\vfi$为欧拉函数,$\ga$为欧拉常数,$N_k$为第一个$k$素数的乘积。在本文中,我们考虑函数$c(n) =(n/\vfi(n)-e^\ga\log\log n)\sqrt{\log n}$。在Riemann假设下,证明了$c(N_k)$是有界的,并给出了明确的界,当Riemann假设不成立时,$c(N_k)$上下无界.

英文摘要:

Let $\vfi$ be Euler's function, $\ga$ be Euler's constant and $N_k$ be the product of the first $k$ primes. In this article, we consider the function $c(n) =(n/\vfi(n)-e^\ga\log\log n)\sqrt{\log n}$. Under Riemann's hypothesis, it is proved that $c(N_k)$ is bounded and explicit bounds are given while, if Riemann's hypothesis fails, $c(N_k)$ is not bounded above or below.
