Shinichi Mochizuki: On the Formalization of IUT: a preliminary progress report
In this talk, we survey preliminary work conducted by my research group at RIMS, Kyoto University, since the fall of 2025 on the long-term project of formalizing IUT (inter-universal Teichmüller theory).

Finally, we discuss in detail, as a sort of case study, the reorganization into suitable blackboxes, from a Lean formalization-oriented point of view, of the logic of the final portion “3.11⇒3.12” of the third paper on IUT, since it is this portion of IUT that has received the most public attention. The skeletal Lean code that we wrote for this portion of IUT constituted a remarkably successful case of the use of Lean as a communication tool.
