Effective construction of irreducible curve singularities
Abdallah Assi, Margherita Barile
We can associate with any irreducible curve singularity (ics) a numerical semigroup. Two ics are said to be equisingular if they have the same semigroup. Two equisingular ics have…
A flatness property for filtered D-modules
F. J. Castro-Jimenez, M. Granger
Let M be a coherent module over the ring D of linear differential operators on an analytic manifold X and let us consider k germs of transverse hypersurfaces at a point x in X. The…
Clifford Theorem for real algebraic curves
Jean-Philippe Monnier
We establish for smooth projective real curves the equivalent of the classical Clifford inequality known for complex curves. We also study the cases when equality holds.
On the formal structure of logarithmic vector fields
Michel Granger, Mathias Schulze
In this article, we prove that a free divisor in a three dimensional complex manifold must be Euler homogeneous in a strong sense if the cohomology of its complement is the hyperco…
On the postulation of s^d fat points in P^d
Laurent Evain
In connection with his counter-example to the fourteenth problem of Hilbert, Nagata formulated a conjecture concerning the postulation of r fat points of the same multiplicity in t…
