This is the repository for Kevin Buzzard's 2022 course on formalising mathmatics in the Lean theorem prover. The course runs from January to March 2022. The material will start appearing on or before 10th January 2022.
If you have Lean 3 and the community tools installed, then it's just a matter of typing
leanproject get ImperialCollegeLondon/formalising-mathematics-2022
into the command line. Instructions for installing Lean 3 and the relevant tools are here.
The course notes are here. They are also currently unfinished, and will grow in parallel with this repo over the period Jan to March 2022.
The accompanying videos are in a YouTube playlist here. As with everything else, this playlist will be built during the period Jan to March 2022.
