Composantes irréductibles de lieux spéciaux d'espaces de modules de courbes, action galoisienne en genre quelconque
Benjamin Collas, Sylvain Maugeais
In this paper we characterise the action of the absolute Galois group on the geometric finite cyclic groups without étale factorization of stack inertia of the profinite geometric…
Aller-retour vers l'inseparable
Sylvain Maugeais
We construct inseparable morphisms between curves of genus that are degenerations of separable morphisms.
Quelques calculs d'espaces sur des courbes
Sylvain Maugeais
We give some properties (cancellation, representability, stratification) of the sheaf R^i f_* G for an affine relative curve f:U -> S admitting a smooth compactification and G a so…
Déformations équivariantes des courbes stables I : Étude cohomologique
Sylvain Maugeais
Let be a field, $C\to \Spec k$ be a stable curve and let be a finite group acting faithfully on the curve $C\to \Spec k$. In this article, we compute the vector space $\Ext…
Espace de modules des courbes hyperelliptiques stables et une inégalité de Cornalba-Harris-Xiao
Sylvain Maugeais
In this paper, we show an inequality between the degrees of the conductor and the Hodge fiber of a hyperelliptic curve above a discrete valuation ring. For that we have to show the…
