On the logarithmic comparison theorem for integrable logarithmic connections
(London Mathematical Society, 2009)Let X be a complex analytic manifold, D ⊂ X a free divisor with jacobian ideal of linear type (e.g. a locally quasi-homogeneous ...

On the minimal positive standardizer of a parabolic subgroup of an Artin–Tits group
(Springer, 2018-09-22)The minimal standardizer of a curve system on a punctured disk is the minimal positive braid that transforms it into a ...

On the modules of m-integrable derivations in non-zero characteristic
(Elsevier, 2012-03-20)Let k be a commutative ring and A a commutative k-algebra. Given a positive integer m, or m = ∞, we say that a k-linear ...

On the number of rational points on curves over finite fields with many automorphisms
(Elsevier, 2013-01)Using Weil descent, we give bounds for the number of rational points on two families of curves over finite fields with a ...

On the rank of an A-hypergeometric D-module versus the normalized volume of A
(Wiley, 2022-03-06)The rank of an A-hypergeometric D-module MA(β), associated with a full rank (d×n)-matrix A and a vector of parameters β∈Cd, ...

On the reduced Bernstein-Sato polynomial of Thom-Sebastiani singularities
(Springer Nature, 2023-08-10)Given two holomorphic functions f and g defined in two respective germs of complex analytic manifolds (X, x) and (Y, y), ...

On the singular braid monoid of an orientable surface
(American Mathematical Society, 2004)In this paper we show that the singular braid monoid of an orientable surface can be embedded in a group. The proof is purely topological, making no use of the monoid presentation.

On the Sn-module structure of the noncommutative harmonics
(Elsevier, 2008-08)Using the a noncommutative version of Chevalley’s theorem due to Bergeron, Reutenauer, Rosas, and Zabrocki we compute the ...

On the structure of the centralizer of a braid
(Elsevier, 2004)The mixed braid groups are the subgroups of Artin braid groups whose elements preserve a given partition of the base ...

On the ubiquity of trivial torsion on elliptic curves
(Springer, 2010-08)The purpose of this paper is to give a down-to-earth proof of the well–known fact that a randomly chosen elliptic curve over the rationals is most likely to have trivial torsion.

On the unit of a monoidal model category
(Elsevier, 2015-08-15)In this paper we show how to modify cofibrations in a monoidal model category so that the tensor unit becomes cofibrant ...

Ordering pure braid groups on compact, connected surfaces
(University of California, 2002-04)We prove that the pure braid groups on compact, connected, orientable surfaces are bi-orderable, and that the pure braid groups on compact, connected non-orientable surfaces have generalized torsion, thus they are not bi-orderable.

Parabolic subgroups acting on the additional length graph
(Geometric & Topology Publications, 2021-08-18)Let A ≠ A 1 , A 2 , I 2 m be an irreducible Artin–Tits group of spherical type. We show that the periodic ...

Parabolic subgroups of large-type Artin groups
(Cambridge University Press, 2022-09-12)We show that the geometric realisation of the poset of proper parabolic subgroups of a large-type Artin group has a systolic ...

Partial symmetries of iterated plethysms
(Springer, 2023-05-03)This work highlights the existence of partial symmetries in large families of iterated plethystic coefficients. The ...

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.

Presentations for the monoids of singular braids on closed surfaces
(Taylor & Francis, 2002)We give presentations, in terms of generators and relations, for the monoids SBn(M) of singular braids on closed surfaces. ...
