RIKEN Mathematics & AI Symposium 2026

Mathematics and AI: Tokyo Symposium on the Mathematical Sciences and Formal Reasoning

This international symposium brings together leading researchers in the mathematical sciences, formal reasoning, and AI-driven discovery to explore the evolving relationship between mathematics and AI. The meeting will examine how AI is reshaping mathematical research, from conjecture and proof to formalization and discovery, while mathematics continues to provide fundamental ideas for the theory and reliability of modern AI. Held in Tokyo, the symposium aims to foster international dialogue and new collaborations at the interface of mathematics and AI.

Tutorial Lectures: Tuesday, August 18
