The idea of this web-site is that there is a place for open development of mathematics next to the current scientific model. For more information on how this is supposed to work, please see the general discussion on the algebraic_geometry mailing list and its archives.
The documents on this website are published under the GFDL.
This is the first project started on the open source model in algebraic geometry. Its aim is mainly to explain and elucidate how to work with algebraic stacks in algebraic geometry. We will provide proofs of all results, apart from some basic facts from algebra, set theory, sheaf theory. Sometimes we will avoid stating (and proving) a result in its utmost generality to avoid the project getting too large. Sometimes as well we will use an advanced result that has a good exposition in the mathematical literature, however, in general we try to avoid this.
To contribute please start reading the other documents in this directory. Feel free to point out typos, mistakes on the mailing list for this project or even better, submit ``patches'' and/or new files.
