Formalizing Discrete Differential Geometry in Lean 3.
I originally planned to use a blueprint website, but stopped using it at some point. I have left the unfinished website up. More information about it below.
Details will be found on the project website.
Much of the project infrastructure has been adapted from the unit fractions project, the sphere eversion project, and the liquid tensor experiment.
To build the Lean files of this project, you need to have a working version of Lean. See the installation instructions (under Regular install).
To obtain this repo, run leanproject get https://github.com/maxwell-thum/DDG_Lean3. If you already have the repo, you can
update it with git pull followed by leanproject get-mathlib-cache.
To build the repo, run leanproject build.
To build the web version of the blue print, you need a working LaTeX installation. Furthermore, you need some packages:
sudo apt install graphviz libgraphviz-dev
pip3 install invoke pandoc
cd .. # go to folder where you are happy clone git repos
git clone [email protected]:plastex/plastex
pip3 install ./plastex
git clone [email protected]:PatrickMassot/leanblueprint
pip3 install ./leanblueprint
cd DDG_Lean3
To actually build the blueprint, run
leanproject get-mathlib-cache
leanproject build
inv all
To view the web-version of the blueprint locally, run inv serve and navigate to
http://localhost:8000/ in your favorite browser.
