关于整数的因子分解数

On the number of factorizations of an integer

R. Balasubramanian, Priyamvad Srivastav

摘要:

令$f(n)$表示将正整数$n$无序分解为大于$1$的因子的次数。我们发现,$f(n)$的不同值的数量,小于或等于$x$,最多是$\exp \left( C \sqrt{\frac{\log x}{\log \log x}} \left( 1 + o(1) \right) \right)$,其中$C=2π\sqrt{2/3}$和$x$是足够大的。这改进了第一作者和F.卢卡

英文摘要:

Let $f(n)$ denote the number of unordered factorizations of a positive integer $n$ into factors larger than $1$. We show that the number of distinct values of $f(n)$, less than or equal to $x$, is at most $\exp \left( C \sqrt{\frac{\log x}{\log \log x}} \left( 1 + o(1) \right) \right)$, where $C=2π\sqrt{2/3}$ and $x$ is sufficiently large. This improves upon a previous result of the first author and F. Luca.
