They claim: Brauer's k(B)-conjecture for 2-blocks (2611.00426), the Hausel–Rodriguez-Villegas conjecture on mixed Hodge polynomials of twisted GL_n character varieties (2611.00427), Lusztig's conjectures P1–P15 for extended affine Weyl groups with positive weights (2611.00411), Lusztig's connectedness conjecture for left cells in finite Weyl groups (2611.00406), the scheme-theoretic Humphreys conjectures (2611.00408) and the Shapiro–Shapiro conjecture for ordered positive flags (2611.00409). GPT-6-Pro did the research, review and writing. ## Key facts - Brauer's k(B)-conjecture (1954), p = 2 case: 'every 2-block of a finite group has at most as many ordinary irreducible characters as the order of its defect groups'; 'GPT-6-Pro was used during approximately 29 hours of documented research sessions' ([2611.00426](https://hexagonmath.org/abs/2611.00426)) - Hausel–Rodriguez-Villegas conjecture: 'two research sessions totalling approximately 22 hours' ([2611.00427](https://hexagonmath.org/abs/2611.00427)) - Lusztig's P1–P15 for extended affine Weyl groups with positive integer weights: 'more than 110 hours of documented research-session time across fourteen rounds' ([2611.00411](https://hexagonmath.org/abs/2611.00411)); Lusztig's connectedness conjecture in finite type, every equal-parameter Kazhdan–Lusztig left cell connected by simple left multiplications, from 'approximately 88 hours' over twelve sessions ([2611.00406](https://hexagonmath.org/abs/2611.00406)) - Scheme-theoretic Humphreys conjectures for p above the Coxeter number, 'approximately 2.11 hours' ([2611.00408](https://hexagonmath.org/abs/2611.00408)); Shapiro–Shapiro conjecture for ordered totally positive flags, '10.9 hours' ([2611.00409](https://hexagonmath.org/abs/2611.00409)) - Each provenance statement ends: 'A review by Rethlas-OSV will be added later' (Rethlas: an agent system by Liang Xiao and Bin Dong's group). Hexagon does not judge correctness; no arXiv copies, Lean files or expert reactions found by 14 Nov - Context: Tang has posted dozens of such deposits since October (e.g. Kamnitzer's MV = theta conjecture, Gorenstein symmetry; see the 29 Oct, 4 Nov and 10 Nov listings). The positive-flag Shapiro–Shapiro case and some Lusztig cases may overlap known results (Mukhin–Tarasov–Varchenko proved the original Shapiro conjecture; Lusztig's P1–P15 are known in the equal-parameter case); the deposits' novelty claims are unchecked ## What happened Qiyue Tang, listed on Hexagon as a Tsinghua mathematician, deposited six papers on 13 Nov, each titled as a proof of a named conjecture. Each says GPT-6-Pro did the research, checked the arguments and polished the text, gives the session time, and states that no human has checked or understood the contribution. ## Why it matters Brauer's k(B)-conjecture and the Hausel–Rodriguez-Villegas conjecture are well known; a correct proof of either would be major. As deposited, these are unverified model outputs. The batch shows how fast claims on famous problems now appear compared with the capacity to check them, the problem MathHelm ([2026-11-13-mathhelm-forum-ai-generated-papers](https://postcutoff.com/e/2026-11-13-mathhelm-forum-ai-generated-papers/index.md)) was set up to address. ## What is disputed or not yet verified - Verification: Unverified claim (Hexagon deposits, no human check, no Lean) ## Your AI and this story - GPT-6 Astra (training cutoff April 2026): 197 days after its cutoff - Claude Opus 5.5 (training cutoff June 2026): 136 days after its cutoff - Gemini 4 Hydrogen (training cutoff March 2026): 227 days after its cutoff - Grok 4.7 (training cutoff May 2026): 166 days after its cutoff ## Sources 1.
