SUMMARY:Sur la stabilité des fibrés tangents d'espaces hermitiens symétriques
DESCRIPTION:Soit Y un espace hermitien symétrique. Son fibré tangent est stable au sens de la pente par rapport à la polarisation canonique. Dans cet exposé\, on s?RTMintéressera à la question de savoir en restriction à quelles sous-variétés X de Y ce fibré reste stable. Plusieurs résultats généraux montrent que c?RTMest le cas pour des intersections complètes de grand degré. Par un argument cohomologique\, nous montrerons que c?RTMest en fait le cas pour toutes les intersections complètes de dimension au moins 3\, en dehors d?RTMune liste de contre-exemples évidents. En dimension 2\, nous finirons par étudier le cas ou Y est un solide quadratique et X une surface de del Pezzo de degré 4.

SUMMARY:Cohomology jump loci
DESCRIPTION:Firstly\, we propose and illustrate a refinement of Deligne?RTMs principle: every infinitesimal deformation problem over a field of characteristic zero with cohomology constraints is governed by a differential graded Lie algebra together with a module. Secondly\, we review recent results about the global structure of cohomology jump loci of rank one local systems. Finally\, we address future directions for other types of jump loci. All this is joint work with Botong Wang.

SUMMARY:Semisimplicité de la cohomologie quantique de certaines variétés de Fano
DESCRIPTION:Je donnerai une condition suffisante pour que l’anneau de cohomologie quantique soit semisimple et expliquerai comment l’appliquer à certaines variétés de Fano ayant un grand indice. Je considérerai tout particulièrement l’exemple des sections linéaires de grassmanniennes de droites.

SUMMARY:The Base Point Free Theorem in positive characteristic
DESCRIPTION:In positive characteristic the Base Point Free Theorem is still an open problem. In a joint work with Jakub Witaszek and Yusuke Nakamura\, we proved the Base Point Free theorem for varieties of dimension three with log canonical singularities defined over the algebraic closure of a finite field. I will give an introduction to the problem and describe the tools that we used in the proof.

SUMMARY:Resolution of singularities by p-alterations
DESCRIPTION:de Jong proved that any variety X can be desingularized by an alteration f:X’–>X\, i.e. a proper surjective generically finite morphism. This was strengthened by Gabber as follows: f can be chosen of degree prime to a fixed prime l invertible on X.In this talk\, I’ll tell about the most recent progress on the subject: if X is of finite type over a quasi-excellent threefold then one can desingularize X by an alteration whose degree is only divisible by primes non-invertible on X. We will also discuss finer results that deal with divisors and desingularize morphisms in the sense of semistable reduction.
