Good moduli spaces for Artin stacks

Nous développons une théorie qui associe des espaces de modules ayant de bonnes propriétés géométriques des champs d’Artin arbitraires, généralisant ainsi la théorie géométrique des invariants de Mumford et les « champs modérés ».

We develop the theory of associating moduli spaces with nice geometric properties to arbitrary Artin stacks generalizing Mumford’s geometric invariant theory and tame stacks.
