README snapshot
This repository contains Lean 4 formulations of the seven Millennium Prize Problems described by the Clay Mathematics Institute. It focuses on the problem statements and the mathematics needed to express them—not on claiming solutions. p align="center" img src="millennium_problems.png" alt="The seven Millennium Prize Problems" /p The first command checks the Lean development.
