A Coq library for Homotopy Type Theory
Role in this project:
Back-end Developer
Back-end DeveloperContributions:1 review, 354 commits, 140 PRs in 7 years 11 months
Contributions summary:Bas contributed to the Coq library for Homotopy Type Theory by adding and modifying tactics and working on core mathematical structures. They implemented and refined tactics, such as the "done" tactic, to aid in the formal verification process. Furthermore, they worked on porting and extending existing mathematical constructs such as HSet, demonstrating a focus on core mathematical foundations within the Coq environment. The user also contributed to the Overture, HSet, and HLevel files, which are central to the library.
