Cohomology of the complement of a free divisor
(American Mathematical Society, 1996-08)
We prove that if D is a "strongly quasihomogeneous" free divi- sor in the Stein manifold X, and U is its complement, then the de Rham cohomology of U can be computed as the cohomology of the complex of mero- morphic ...

Logarithmic differential operators and logarithmic de Rham complexes relative to a free divisor
(Elsevier, 1999)
We prove a structure theorem for differential operators in the 0-th term of the V-filtration relative to a free divisor. manifold. As an application, we give a formula for the logarithmic de Rham complex with respect to a ...

Le théorème de continuité de la division dans les anneaux d'opérateurs différentiels
(De Gruyter, 1998)
In this paper we prove the continuity of Weierstrass-Hironaka division of finite order linear differential operators over a complex analytic manifold X with respect to the induced topology by a canonical one of Fréchet ...

Combinatorics of syzygies for semigroup algebras
(Universitat de Barcelona, 1998)
We describe how the graded minimal resolution of certain semigroup algebras is related to the combinatorics of some simplicial complexes. We obtain characterizations of the Cohen-Macaulay and Gorenstein conditions. The ...
