Sur les singularités isolées d'intersections complètes quasi-homogènes

Marc Giusti (1977)

Annales de l'institut Fourier

Le résultat principal de cet article est une formule explicite donnant le nombre de Milnor d’une singularité isolée d’intersection complète quasi-homogène d’une courbe de C 3 en fonction des degrés et des poids. Ce calcul effectué par des méthodes topologiques repose sur le théorème suivant : la fibre de Milnor d’une singularité isolée d’intersection complète quasi-homogène ne dépend que des degrés et des poids à difféomorphisme près. Une autre conséquence de ce théorème est l’existence d’une morsification...

The Denef-Loeser series for toric surface singularities.

Monique Lejeune-Jalabert, Ana J. Reguera (2003)

Revista Matemática Iberoamericana

Let H denote the set of formal ares going through a singular point of an algebraic variety V defined over an algebraically closed field k of charactcristic zcro. In the late sixties, J, Nash has observed that for any nonnegative integer s, the set js(H) of s-jets of ares in H is a constructible subset of some affine space. Recently (1999), J. Denef and F. Loeser have proved that the Poincaré series associated with the image of js(H) in some suitable localization of the Grothendieck ring of algebraic...

The end curve theorem for normal complex surface singularities

Walter D. Neumann, Jonathan Wahl (2010)

Journal of the European Mathematical Society

We prove the “End Curve Theorem,” which states that a normal surface singularity ( X , o ) with rational homology sphere link Σ is a splice quotient singularity if and only if it has an end curve function for each leaf of a good resolution tree. An “end curve function” is an analytic function ( X , o ) ( , 0 ) whose zero set intersects Σ in the knot given by a meridian curve of the exceptional curve corresponding to the given leaf. A “splice quotient singularity” ( X , o ) is described by giving an explicit set of equations describing...
