关于伪奇完满数的稠密性

On the Density of Spoof Odd Perfect Numbers

László Tóth

摘要:

本文研究了奇正整数集合$\mathcal{S}$的性质${2n}/{σ(n)} - 1 = 1/x$,对于正整数$x$,与奇完全数和奇“欺骗完全数”有关的集合。结果发现,如果$D=pq$表示一个伪奇完全数,而不是笛卡尔的例子,则$q>10^{12}$是伪素因子$p$.此外,我们发现不规则的整数$n\in\mathcal{S}$和研究方面的密度,导致我们推测,$\mathcal{S}$低于$k$的数量是$\sim10 \log(k)$。

英文摘要:

We study the set $\mathcal{S}$ of odd positive integers $n$ with the property ${2n}/{σ(n)} - 1 = 1/x$, for positive integer $x$, i.e., the set that relates to odd perfect and odd "spoof perfect" numbers. As a consequence, we find that if $D=pq$ denotes a spoof odd perfect number other than Descartes' example, with pseudo-prime factor $p$, then $q>10^{12}$. Furthermore, we find irregularities in the ending digits of integers $n\in\mathcal{S}$ and study aspects of its density, leading us to conjecture that the amount of numbers in $\mathcal{S}$ below $k$ is $\sim10 \log(k)$.
