## Question

[odd-perfect-numbers] Produce a status report or a checkable solution for: Existence of odd perfect numbers. Statement: Does there exist an odd perfect number? A perfect number equals the sum of its proper divisors (sigma(n)=2n). Even perfect numbers are classified via Euclid-Euler. No odd perfect number is known. If unsolved, report the best partial results and references. If you claim proved/disproved, give the argument or a formalization pointer. Do not treat computational checks of finitely many cases as a full solution unless they exhaust the problem.
