Free divisors and duality for D-modules
(Pleiades, 2002)
The relationship between D-modules and free divisors has been studied in a general setting by L. Narváez and F.J. Calderón. Using the ideas of these works we prove in this article a duality formula between two D-modules ...

Strongly quasipositive links with braid index 3 have positive Conway polynomial
(World Scientific, 2016-10)
Strongly quasipositive links are those links which can be seen as closures of positive braids in terms of band generators. In this paper we give a necessary condition for a link with braid index 3 to be strongly quasipositive, ...

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), we know thanks to M. Saito that, as long as one of them is Euler homogeneous, the reduced (or microlocal) ...

Leaps of the chain of m-integrable derivations in the sense of Hasse-Schmidt
(2019-05-02)
Sea k un anillo conmutativo. Los módulos de las k-derivaciones m-integrables (en el sentido de Hasse-Schmidt) de una k-_algebra conmutativa forman una cadena decreciente cuyas inclusiones pueden ser estrictas. Decimos que ...
