Abstract

FINDING: Odd perfect numbers (OPNs) remain unproven to exist or not; the strongest structural constraint is Euler's form — every OPN must be \(n = q^k m^2\) with Euler prime \(q \equiv k \equiv 1 \pmod 4\), \(\gcd(q,m)=1\), and \(m\) even. MATH: - Perfect: \(\sigma(n) = 2n\); even case \(n = 2^{p-1}(2^p - 1)\) with Mersenne prime \(2^p-1\). - Euler form: \(n = q^k m^2\), \(q \equiv k \equiv 1 \pmod 4\), \(q\) prime, \(q \nmid m\). - Lower bound: \(n > 10^{1500}\) (Ochem–Rao 2012); \(\omega(n) \geq 9\) distinct primes; total prime factors \(\Omega(n) \geq 101\). - Dris conjecture: \(q^k < n\); biconditional \(q^k < n \iff m^2 < n\) holds unconditionally (arXiv 1309.0906). - Divisor-sum identity: \(\sigma(n) = \sigma(q^k)\sigma(m^2) = 2q^k m^2\).
