Logarithmic Geometry and Algebraic Stacks
نویسنده
چکیده
– We construct algebraic moduli stacks of log structures and give stack-theoretic interpretations of K. Kato’s notions of log flat, log smooth, and log étale morphisms. In the last section we describe the local structure of these moduli stacks in terms of toric stacks. 2003 Elsevier SAS RÉSUMÉ. – Nous construisons des champs algébriques classifiant les structures logarithmiques et donnons de nouvelles interprétations, fondées sur la théorie des champs, des concepts de morphisme log plat, log lisse, et log étale introduits par K. Kato. Dans la dernière partie, nous décrivons la structure locale de ces champs en termes de champs toriques. 2003 Elsevier SAS

متن کاملOn Quotient Stacks
A natural problem in algebraic geometry is the formation of quotients. This is particularly important in the theory of moduli, where many moduli spaces are naturally constructed as quotients of parameter spaces by linear algebraic groups. Examples of quotient moduli spaces include moduli spaces of curves, stable maps and stable vector bundles (with fixed determinant). Unfortunately, the quotien...

متن کاملUnification and Logarithmic Space
We present an algebraic characterization of the complexity classes Logspace and NLogspace, using an algebra with a composition law based on unification. This new bridge between unification and complexity classes is inspired from proof theory and more specifically linear logic and Geometry of Interaction. We show how unification can be used to build a model of computation by means of specific su...
