Bounds for Odd $k$ -Perfect Numbers

Shi-Chao Chen, Hao Luo

Let $k \geq 2$ be an integer. A natural number $n$ is called $k$ -perfect if $σ (n) = k n .$ For any integer $r \geq 1$ we prove that the number of odd $k$ -perfect numbers with at most $r$ dis…

Odd Multiperfect Numbers

Shi-Chao Chen, Hao Luo

A natural number $n$ is called {\it multiperfect} or {\it $k$ -perfect} for integer $k \geq 2$ if $σ (n) = k n$ , where $σ (n)$ is the sum of the positive divisors of $n$ . In this paper, we e…
