Submit a proof digest.

Send a link to a written explanation or a video of at most ten minutes. Include a plain-text overview of the result, the proof idea and how your explanation helps its intended audience. Historical context, applications and worked examples may be included where useful. Competition entries are due by 30 November 2026.

This prepares an email; it does not submit a web form. Your draft stays in this page until you copy it or open your email app. Send the draft from your own mailbox to the judges’ shared Gmail address shown below. If the address is unavailable, email submission is temporarily disabled.

Proofs already in the original collection only. This library and competition accept explanations of existing proofs in the repository. Propose new problems or additional solutions there through a pull request.

How did you use AI? This entry explains a proof already in the Open Problems in Numerical Linear Algebra repository.

Before you send

Where to host your work

Put your paper on Zenodo, arXiv or ResearchGate, or your video on YouTube or Vimeo. Provide the readable overview or transcript in the email itself.

We do not accept attachments, archives, installers or requests to run code. The website never fetches your entry link.

External hosts have their own terms, privacy rules and age requirements. A permitted link is not a safety certificate.

Review and publication

The organisers review your email and share it privately with the judging panel as needed. They may ask for clarification.

Accepted papers and videos receive library pages with a DOI for an archived version. Before publication, the organisers will agree the public text, digest authorship, source citation and archival deposit with you. Video entries include a transcript. Contact details and private correspondence do not belong in the public library.
