This repo is old Lean 3 code. A Lean 4 version of this course is here.
This is the repository for Kevin Buzzard's 2022 course on formalising mathmatics in the Lean theorem prover. The course ran from January to March 2022. Note: the 2023 version of the course is here.
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. Note: the 2023 course notes are more up to date.
