Its five listed contributors are\nspecialists in tensor categories, and two of them, Etingof and Ostrik, posed the conjecture with Dave Benson in 2023. The\nprovenance statement says the paper itself was generated by GPT-6 Astra, with the humans asking questions and proposing\nreductions; they say they will turn it into a human-written paper.\n\n## Why it matters\n\nThe conjecture describes all \"reasonable\" symmetric tensor categories in positive characteristic, an analogue of Deligne's\ntheorem in characteristic zero. It is unusual that the conjecture's own authors co-sign a deposit that they describe as written\nby a model. The claim has not been refereed.","disputed":[{"label":"Verification","text":"Unrefereed Hexagon deposit; partly checked by the contributors","sources":[]}],"related":[{"id":"2026-11-11-ai-assisted-results-november-11-listing","url":"https://postcutoff.com/e/2026-11-11-ai-assisted-results-november-11-listing/","date":"2026-11-11","date_precision":"day","short_title":"AI-assisted results, 11 Nov: arXiv and Hexagon","deck":null,"takeaway":"Own entries today: Smale's constant = 4 (Goel, Lean), Talagrand's Ultimate Matching Conjecture (GPT-6), the Benson–Etingof–Ostrik conjecture (GPT-6 Astra), large triangles in planar dense sets (GPT-6 Astra Pro) and explicit RIP matrices (GPT-6 Astra).
