Welcome to the Clowder Project!

The Clowder Project is an online reference work and wiki for category theory and ma­the­ma­ti­cs. It is built using Gerby, created by Pieter Belmans and Raymond Cheng, which is a fork of plas­TeX. The Clowder Project follows the massively collaborative model started by the Stacks Project, and aims to become the equivalent of it for ca­te­go­ry theory.

All comments, no matter how small, are ex­tre­me­ly welcome, as are contributions.

For more information about the Clowder Project, see Chapter 1: Introduction.

Warning: Clowder is severely incomplete, and the current content is not re­pre­sen­ta­ti­ve of what the project hopes to be. See the Progress page for more details.

The Clowder Project currently receives $30 monthly. A larger monthly donation pool would allow the project maintainer to devote (many!) more hours towards improving and ex­pan­ding Clowder (rather than on semi-random freelance work to make ends meet), directly impacting how quickly new updates and content come out.
