Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
This abstraction was added when we started Lean. We wanted to focus on nonlinear arithmetic and support dReal. The zpz module was going to be used to implement polynomial factorization procedures similar to the ones in Z3 and computer algebra systems. This is not a goal for the Lean project anymore. |
