Univalent Mathematics

This Coq library aims to formalize a substantial body of mathematics using the univalent point of view.

Trying out UniMath

You can try out UniMath in the browser by clicking here. For instance, you can run the files from the School on Univalent Mathematics in the browser.

Using UniMath on your computer

To install UniMath on your computer, there are two options:

• Install a released binary version of UniMath via the Coq Platform.
• To develop, and contribute to, UniMath, you should compile the latest version of UniMath yourself - see INSTALL.md.

Usage

See USAGE.md

Contents

The UniMath subdirectory contains various packages of formalized mathematics. For more information, see the UniMath Table of Contents.

Some scientific articles describing the contents of the UniMath library or work using it are listed in the wiki.

Discussing UniMath & Getting Help

• Questions about the UniMath library, compilation, and installation of UniMath, etc., can be asked in the UniMath Zulip (click here to register) or on the UniMath mailing list (archived in a Google Group).
• Bugs should be reported in our UniMath bug tracker on GitHub.

Citing UniMath

To cite UniMath in your article, you can use the following bibtex item:

@Misc{UniMath,
    author = {Voevodsky, Vladimir and Ahrens, Benedikt and Grayson, Daniel and others},
    title = {UniMath --- a computer-checked library of univalent mathematics},
    url = {https://github.com/UniMath/UniMath},
    howpublished = {available at \url{http://unimath.org}},
    doi          = {10.5281/zenodo.8427604},
    url          = {https://doi.org/10.5281/zenodo.8427604}
 }

Note that this requires \usepackage{url} or \usepackage{hyperref}.

The UniMath Coordinating Committee

The UniMath project was started in 2014 by merging the repository Foundations, by Vladimir Voevodsky (written in 2010), with two repositories based on it: rezk_completion, by Benedikt Ahrens, and Ktheory, by Daniel Grayson. Vladimir Voevodsky was a member of the team until his death in September, 2017.

The current members of the UniMath Coordinating Committee are:

• Benedikt Ahrens
• Daniel Grayson
• Michael Lindgren
• Peter LeFanu Lumsdaine
• Ralph Matthes
• Niels van der Weide

Acknowledgments

The UniMath development team gratefully acknowledges the great work by the Coq development team in providing the Coq proof assistant, as well as their support in keeping UniMath compatible with Coq.
