Two Mayer-Vietoris Spectral Sequences for D-modules
(American Mathematical Society, 2015-03-18)
We provide two Mayer-Vietoris-like spectral sequences related to the localization over the complement of a closed subvariety of an algebraic variety by using techniques from $\mathcal{D}$-modules and homological algebra. ...

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 graded Frobenius series for their two sets of noncommutative harmonics with respect to the left ...

Milne's volume function and vector symmetric polynomials
(Elsevier, 2009-05)
The number of real roots of a system of polynomial equations fitting inside a given box can be counted using a vector symmetric polynomial introduced by P. Milne, the volume function. We provide the expansion of Milne’s ...

Acylindrical hyperbolicity and Artin-Tits groups of spherical type
(Springer, 2017)
We prove that, for any irreducible Artin-Tits group of spherical type G, the quotient of G by its center is acylindrically hyperbolic. This is achieved by studying the additional length graph associated to the classical ...

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, is known to be the normalized volume of A, denoted vol(A), when β lies outside the exceptional ...

Toda brackets and cup-one squares for ring spectra
(Taylor & Francis, 2009)
In this paper we prove the laws of Toda brackets on the homotopy groups of a connective ring spectrum and the laws of the cup-one square in the homotopy groups of a commutative connective ring spectrum.

The root extraction problem for generic braids
(MDPI, 2019-10)
We show that, generically, finding the k-th root of a braid is very fast. More precisely, we provide an algorithm which, given a braid x on n strands and canonical length l, and an integer k > 1, computes a k-th root of ...

Triangulated categories without models
(Springer, 2007-11)
We exhibit examples of triangulated categories which are neither the stable category of a Frobenius category nor a full triangulated subcategory of the homotopy category of a stable model category. Even more drastically ...

Types modulo ℓ pour les formes intérieures de GLn sur un corps local non archimédien
(London Mathematical Society, 2014-10-04)
Let F be a non-Archimedean locally compact field of residue characteristic p, let D be a finitedimensional central division F-algebra and let be a prime number different from p. We develop a theory of ℓ-modular types for ...
