On a Recursive Integer Sequence Implying the Nonexistence of Odd Perfect Numbers

Number Theory 2025-06-04 v2

Abstract

We define a sequence of positive integers recursively, where each term is determined as follows: starting with a given positive integer, if the term is odd, the next is the sum of its positive divisors; if the term is even, the subsequent term is half the term. In this paper, we conjecture that this sequence eventually reaches one for all initial values. Furthermore, we classify a family of integers for which this conjecture holds.
