ayushkhaitan, with Ben Chow, Yuan Liao and Ziyang Qin, announced the completion of a full Lean formalization of the Hamilton–Perelman proof of the Poincaré conjecture.
- The formalized proof spans roughly 4.7 million lines of code, written in about two weeks
- The work was supported by DARPA's expMath program
- A milestone for formal verification of major mathematics
