Analytic implications from the remainder term of the prime number theorem

Abstract

It is well known that the distribution of the prime numbers plays a central role in number theory. It has been known, since Riemann's memoir in 1860, that the distribution of prime numbers can be described by the zero-free region of the Riemann zeta function $\zeta (s)$. This function has infinitely many zeros and a unique pole at $s=1$. Those zeros at $s=-2,-4,-6,...$ are known as trivial zeros. The nontrivial zeros of $\zeta (s)$ are all located in the so-called critical strip $0<\Re (s)<1$. Define $\Lambda (n)=\log p$ whenever $n =p\sp{m}$ for a prime number $p$ and a positive integer $m$, and zero otherwise. Let $x\ge 2$. The $\psi$-form of the prime number theorem is $ψ(x) =\sum\sb{n \le x}Λ(n) =x +O\bigl(x\sp{1-H(x)} \log\sp{2} x\big)$, where the sum runs through the set of positive integers and $H(x)$ is a certain function of $x$ with $\frac{1}{2}\le H(x)<1$. Turán proved in 1950 that this $\psi$-form implies that there are no zeros of $\zeta (s)$ for $\Re (s)>h(t)$, where $t=\Im (s)$, and $h(t)$ is a function connected to $H(x)$ in a certain way with $1/2\le h(t)<1$ but both $H(x)$ and $h(t)$ are close to 1. We prove results similar to Turán's where $\frac{1}{2}\le H(x)<1$ and $\frac{1}{2}\le h(t)<1$ in altered forms without any other restrictions. The proof involves slightly revising and applying Turán's power sum method.
