Encyclopedia of Varieties, Schemes, Stacks, and Singularities Wiki



Welcome to the Encyclopedia of Varieties, Schemes, Stacks, and Singularities Wiki
This wiki is intended to be an easily searchable collection of examples of varieties, schemes, and stacks (embedded and abstract), as well as their subvariety/scheme/stack structure, their singularities, connections and maps between them, as well as useful facts and pictures. As long as I am the sole contributor, it will be heavily slanted towards projective varieties over C, especially things related to moduli of curves.

There is an incomplete to-do list here
