Abstract

For a positive integer nn, if σ(n)σ(n)denotes the sum of the positive divisors of nn, then nnis called a deficient perfect number if σ(n)=2n−dσ(n)=2n−dfor some positive divisor ddof nn. In this paper, we prove some results about odd deficient perfect numbers with four distinct prime factors.
