Extention of Finite Solvable Torsors over a Curve

, 2010
Let $R$ be a discrete valuation ring with fraction field $K$ and with algebraically closed residue field of positive characteristic $p$. Let $X$ be a smooth fibered surface over $R$ with geometrically connected fibers endowed with a section $x\in X(R ...

The moduli stack of $G$-bundles [PDF]

, 2011
In this paper, we give an expository account of the geometric properties of the moduli stack of $G$-bundles. For $G$ an algebraic group over a base field and $X \to S$ a flat, finitely presented, projective morphism of schemes, we give a complete proof ...

Survey on some aspects of Lefschetz theorems in algebraic geometry

, 2017
We survey classical material around Lefschetz theorems for fundamental groups, and show the relation to parts of Deligne's program in Weil II. The notes are based on some aspects of the material for the Santal\'o lectures at the Universidad Complutense

Quelque part, une brique : réinventer le travail dans l’Italie d’après-guerre

Perspective
In 1949, Italian brick manufacturer Giuseppe Verzocchi commissioned seventy paintings from the same number of artists on the theme of labour. Presented at the Venice Biennale the following year, these works were donated in 1961 to the Pinacoteca in Forli,

Euler Sequence and Koszul complex of a module

, 2015
We construct relative and global Euler sequences of a module. We apply it to prove some acyclicity results of the Koszul complex of a module and to compute the cohomology of the sheaves of (relative and absolute) differential $p$-forms of a projective ...

Two ways to degenerate the Jacobian are the same

, 2017
A basic technique for studying a family of Jacobian varieties is to extend the family by adding degenerate fibers. Constructing an extension requires a choice of fibers, and one typically chooses to include either degenerate group varieties or degenerate

Detection by regular schemes in degree two

, 2014
Using Lipman's results on resolution of two-dimensional singularities, we provide a form of resolution of singularities in codimension two for reduced quasi-excellent schemes.

Quand les châteaux étaient peints

Bulletin du Centre de Recherche du Château de Versailles, 2006
French architecture has the reputation of always having favoured the use of materials left in their natural state. However, closer examination of monuments reveals that the facades and roofs of the Renaissance and classical periods were often painted ...
