Its most extensive mathematical library, [mathlib](https://leanprover-community.github.io/index.html), contains many theorems and definitions and theorems from various areas of math.\n\nThe plan for this hands-on session:\n\n- Understand why it might be beneficial to use a theorem prover and how it works.\n- Demo the current capabilities of Lean/mathlib and its ecosystem.\n- Get you hands dirty by trying it out yourself: you'll have the opportunity to prove a lemma!\n\n## Prerequisites\n\nWe don't assume any familiarity with Lean/mathlib.\nHowever, you will need some way to run Lean on your computer.\nThere are different options:\n\n - *The best way*: [Install lean on your computer](https://leanprover-community.github.io/get_started.html)\n - *The fast way*: [Try lean online](https://live.lean-lang.org/)\n - *Another way*: [Use gitpod](https://gitpod.io/new/#/https://github.com/mo271/MathlibSynergies)\n\n\n If you are new to Lean/mathlib, a fun way to begin is by playing the [the natural number game](https://adam.math.hhu.de/)!\n\nIn order to start with the files in this repo, you install lean on your computer (see link above)\nyou clone this repo and run\n```shell\nlake exe cache get\nlake build\ncode .\n```\nThe last step only opens vscode in case you want to use that.\n\n\n## Resources\n\nDocs, Tutorials, search engines\n\n - [mathlib4 documentation](https://leanprover-community.github.io/mathlib4_docs/)\n - [Mathematics in Lean tutorial](https://leanprover-community.github.io/mathematics_in_lean/)\n - [Moogle: Semantic search over mathlib4](https://www.moogle.ai/)\n - [Loogle searches of Lean and Mathlib definitions and theorems.](https://loogle.lean-lang.org/)\n - [abbreviations.json](https://github.com/leanprover/vscode-lean4/blob/master/vscode-lean4/src/abbreviation/abbreviations.json) for a list of symbols one can get by typing `\\` in vscode.\n\nExample projects:\n\n  - [The Polynomial Freiman-Ruzsa Conjecture](https://teorth.github.io/pfr/) [blueprint](https://teorth.github.io/pfr/blueprint/)\n  - [Sphere eversion](https://leanprover-community.github.io/sphere-eversion/) [blueprint](https://leanprover-community.github.io/sphere-eversion/blueprint/index.html)\n  - [Prime number theorem](https://github.com/AlexKontorovich/PrimeNumberTheoremAnd/), [blueprint](https://alexkontorovich.github.io/PrimeNumberTheoremAnd/web/)\n  - Your next project here!\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmo271%2Fmathlibsynergies","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmo271%2Fmathlibsynergies","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmo271%2Fmathlibsynergies/lists"}
