math

openai/math · ★ 15K

A public catalogue of 719 mathematical manuscripts grouped into 372 families, written by an internal OpenAI model during evaluations on open research problems. About 42% of top-line results already have Lean formalizations.

+6

leantime

Leantime/leantime · ★ 11.8K

Leantime is an open-source project management system aimed at non-project managers, combining task management, planning, and knowledge tools in one place. It positions itself as simple as Trello but as feature-rich as Jira, and is explicitly designed with ADHD, dyslexia, and autism in mind.

+6

fermats-last-theorem

anthropics/fermats-last-theorem · ★ 1.3K

A complete, machine-checked Lean 4 proof of Fermat's Last Theorem built on Mathlib, following the Frey-Serre-Ribet-Wiles-Taylor-Wiles argument, and cross-checked by two independent kernels.

+5

open-ontologies

fabio-rovai/open-ontologies · ★ 1.1K

Open Ontologies lets you plan, apply and roll back changes to a production ontology: it shows every consequence as a blast-radius report before you apply a change, then hands the reviewer a proof they can re-check without trusting you or the engine.

    NavierStokesAndEuler

    2.1Kopenai/NavierStokesAndEuler · Lean

    This repository contains Lean 4 formalizations (machine-checked formal proofs) of two OpenAI papers: 'Finite time blowup for Navier-Stokes' and 'Finite time blowup for the Euler equation'.

    integer-mult-bounds

    282CrocSwap/integer-mult-bounds · Python

    This is a community research project that tracks and audits incremental improvements to the theoretical time bound for integer multiplication, expressed as a shrinking exponent kappa, conditional on an external OpenAI framework.

    fluid_lean

    268tristanbuckmaster/fluid_lean · Lean

    fluid_lean is a research codebase written in Lean, the programming language and interactive theorem prover used for formalizing mathematics. Judging by its name, it applies Lean to fluid dynamics, the branch of physics that studies how fluids move.

  6. 9

    Comma

    266AFK-surf/Comma · Elixir

    Comma is an open-source, sessionless personal AI agent that turns your requests into persistent Tasks and keeps working on them through autonomous agent loops until they're done, across your computer, phone, and cloud.

  7. 10

    PrimeGaps186

    166openai/PrimeGaps186 · Lean

    This is a Lean 4 formalization proving a bound on gaps between consecutive primes (gap at most 186), along with a Python script that numerically verifies the inputs used by the proof.
