A Survey of Verifiable Mathematical Discovery](https://md.research.elamur.ai/free/en/papers/tzachristas-2026-open-problems-solved-llms-survey/)** *(2026)* Headlines saying LLMs have "solved open problems" in mathematics are often vague. "Open" can mean an improvable bound, a missing construction or an unproven theorem, and the model rarely works without external tools. This survey offers a framework for judging such claims. ## Co-authors here 1 co-author with a page, the most papers together first. - [Georgios Tzachristas](https://md.research.elamur.ai/free/en/authors/georgios-tzachristas/) ×2 ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Big Picture v2: Crafting a Research Narrative](https://md.research.elamur.ai/free/en/venues/bigpicture/) ×2: [Big Picture v2: Crafting a Research Narrative 2026](https://md.research.elamur.ai/free/en/venues/bigpicture/2026/) ×2 Updated 1 November 2026
