A geometric description of the extreme Khovanov cohomology
(Cambridge University Press, 2018-06)We prove that the hypothetical extreme Khovanov cohomology of a link is the cohomology of the independence simplicial ...

Explicit local multiplicative convolution of ℓ-adic sheaves
(European Mathematical Society, 2018)We give explicit formulas for the local multiplicative convolution functors, which express the local monodromies of the ...

Finite monodromy of some families of exponential sums
(Elsevier, 2019-04)Given a prime p and an integer d > 1, we give a numerical criterion to decide whether the ℓ-adic sheaf associated to the ...

Geometric approaches to braid groups and mapping class groups
(Cellule Mathdoc, 2015)These are Lecture Notes of a course given by the author at the School Winter Braids, held at the Université de Pau et des ...

Large Galois images for Jacobian varieties of genus 3 curves
(Polish Academy of Sciences, Institute of Mathematics, 2016)Given a prime number ℓ ≥ 5, we construct an infinite family of three-dimensional abelian varieties over Q such that, for ...

On the centralizer of generic braids
(De Gruyter, 2018-11)We study the centralizer of a braid from the point of view of Garside theory, showing that generically a minimal set of ...

Polynomial braid combing
(Oxford University Press, 2018)We prove that, for n ≥ 3, the minimal dimension of a model of the classifying space of the braid group Bn, and of the pure braid group Pn, with respect to the family of virtually cyclic groups is n.

Reduced Kronecker coefficients and counter-examples to Mulmuley's strong saturation conjecture SH
(Springer, 2009-12)We provide counter–examples to Mulmuley’s strong saturation conjecture (strong SH) for the Kronecker coefficients. This ...

Torsion of rational elliptic curves over quadratic fields II
(Springer, 2016-03)Let E be an elliptic curve defined over Q and let G=E(Q)_tors be the associated torsion group. In a previous paper, the ...
