Axeyum combines SAT and SMT solving, exact computer algebra, proof checking, and a dependency-aware formal library.

Landing page captured for the 2026-09-04 issue.

Field notes

Axeyum organizes its system around five Rust components: SAT, SMT, computer algebra, a Lean-core checker, and a formal library that records dependencies between accepted facts. Its worked example stores an exact Mean Value Theorem witness, c = √3, after independently re-deriving the derivative, interval bounds, and equality p'(c) = 9. The page also exposes an engine identifier, source-build path, artifacts, and planned comparison surfaces against systems including Z3, Lean, SymPy, and mathlib.
