Axiom formalizes the 20-year Stacks Project in Lean as an explorable city for humans and agents

TheTuringPost · x · 2026-11-12

TheTuring Post highlights what Axiom (Carina Hong's team) built for mathematicians: formalizing the Stacks Project — a mathematical reference built over more than 20 years — into Lean, visualized as an explorable city where each district maps to a field of math and tower height shows how many layers a result builds on. Clicking reveals dependencies and dependents.

The most exciting part is the collaboration paradigm: an agent solving one problem can leave behind reusable pieces that another proof, human, or agent can pick up — extending the Stacks Project's intergenerational gift into the AI-agent era.
