My name is Nikolai Arkhipov. I am an independent researcher from Vladivostok, Russia.

I have completed a proof of the Collatz conjecture (3n+1 problem). The manuscript has been submitted to arXiv (math.GM) and is currently awaiting endorsement.

Copies of the work have been sent to several mathematics professors in the United States (including Jeffrey Lagarias and Marc Chamberland). I have not yet received a response, so I am continuing my search for an endorser.

If you are an active researcher with an arXiv account in mathematics and are willing to help — or know someone who might be — please contact me.

Please note: I will not send the full manuscript to unverified individuals. Serious inquiries only.

Thank you.
