Formalization of the Solution to the Hopf Problem
Summary
A GitHub repository formalizes the solution to the Hopf problem, asserting that the six-sphere admits a complex manifold structure compatible with its standard topology. The project includes a Comparator setup inspired by the Formal Conjectures work, build/type-check instructions, and a link to an online type-check demo, illustrating open-source proof engineering for a deep mathematical result.
