Add to ORKGRecently, Pollack and Shevelev introduced the concept of near-perfect numbers in Journal of Number Theory. A positive integer $n$ is called a \emph{near-perfect number} if it is the sum of all of its proper divisors, except for one of them. In this paper, we determine all near-perfect numbers with two distinct prime factors. 10.1017/S000497271300017
In this work we construct a lower bound for an odd perfect number in terms of the number of its dist...
