OpenATP is an open-source Python package providing a common interface for Automated Theorem Proving (ATP)

A Lean 4 + Mathlib proof service for the agent working on your code

Workspace-first orchestration for long-horizon Lean 4 formalization agents.

Interactive Lean 4 + Mathlib formalization from a Claude Code conversation

A calibrated faithfulness screen for informal↔Lean 4 pairs, on the command line and over MCP. Screens only, never certifies.

Fast Lean 4 proof feedback for coding agents. CLI, Python library, and MCP server with warm LeanInteract sessions and cached env reuse.

OPEN PROBLEMS WANT TO STAY OPEN

AI-native math collaboration platform — discussion + leaderboard for Lean 4 formalization agents

Axiom provenance for Lean 4 and Metamath — which step introduced an axiom, and whether the theorem statement required it Website: https://f-keys.com/gonzalgo/

Trusted AI mathematics workbench: ProblemContract to Attempt to verified proof/counterexample bundles with SymPy and Lean evidence gates.

Retrieval-grounded reviewer-memory tool over closed-PR review history of leanprover-community/mathlib4. Indexes ~158k past reviewer comments across ~35k closed PRs to flag concerns past reviewers have raised before.

Self-hostable paraconsistent HoTT LLM-to-Lean acceptance gateway. Runs proof attempts through security preflight, Lean checks, theorem-fingerprint locks, and ShadowHoTT bilattice routing for accept/repair/reject/human-review decisions.

Measure how far informal proofs are from Lean 4: structured readiness reports, mathlib alignment, and reproducible benchmarks.

Machine-checked Lean 4 / mathlib proofs and deterministic, reproducibility-first numerical audits of released PLDR-LLM checkpoints, backing the paper "Power law graph attention: exact generalization of scaled dot-product attention, empirical collapse at inference" (PLDR-LLM / PLGA).

Reproduction of Ax-Prover: a 3-agent LLM framework for automated Lean 4 theorem proving

MCP server for fast local Lean and Mathlib theorem search with tree-sitter indexing and proof probes

A computational and formal workbench around the Riemann zeta function: kernel-checked Lean proofs, ball-arithmetic enclosures, structure-matched negative controls, and the dead ends published beside the results. Makes no claim of progress toward RH.

Lean 4 / Mathlib v4.11.0 formalisation of the kernel dimension theory of the Z/2 connection Laplacian on finite simple graphs, with paper
