关于乘性Erdés差异问题

On the multiplicative Erdős discrepancy problem

Michael Coons

摘要:

早在20世纪30年代,Pál Erdés就证明:{ \em对于任何乘性函数$f:\mathbb{N}\to\{-1,1\}$,部分和$\sum_{n\leq x}f(n)$是无界的。考虑到这个猜想,本文考虑了满足$$\sum_{p\leq x}f(p)=c\cdot\frac{x}{\log x}(1+o(1)).$$的乘性函数$f$.证明了:如果$c>0$,则$f$的部分和是无界的;如果$c<0$,则$μf$的部分和是无界的.本文还讨论了这一结果的推广。

英文摘要:

As early as the 1930s, Pál Erdős conjectured that: {\em for any multiplicative function $f:\mathbb{N}\to\{-1,1\}$, the partial sums $\sum_{n\leq x}f(n)$ are unbounded.} Considering this conjecture, in this paper we consider multiplicative functions $f$ satisfying $$\sum_{p\leq x}f(p)=c\cdot\frac{x}{\log x}(1+o(1)).$$ We prove that if $c>0$ then the partial sums of $f$ are unbounded, and if $c<0$ then the partial sums of $μf$ are unbounded. Extensions of this result are also discussed.
