Indices of 1-forms on an Isolated Complete Intersection Singularity
There are some generalizations of the classical Eisenbud– Levine–Khimshiashvili formula for the index of a singular point of an analytic vector field on R to vector fields on singular varieties. We offer an alternative approach based on the study of indices of 1-forms instead of vector fields. When the variety under consideration is a real isolated complete intersection singularity (icis), we d...
متن کاملRigid and Complete Intersection Lagrangian Singularities
In this article we prove a rigidity theorem for lagrangian singularities by studying the local cohomology of the lagrangian de Rham complex that was introduced in [SvS03]. The result can be applied to show the rigidity of all open swallowtails of dimension ≥ 2. In the case of lagrangian complete intersection singularities the lagrangian de Rham complex turns out to be perverse. We also show tha...
متن کاملPolar Invariants of Plane Curve Singularities: Intersection Theoretical Approach
This article, based on the talk given by one of the authors at the Pierrettefest in Castro Urdiales in June 2008, is an overview of a number of recent results on the polar invariants of plane curve singularities.
متن کاملComplete Intersection Singularities of Splice Type as Universal Abelian Covers
It has long been known that every quasi-homogeneous normal complex surface singularity with Q–homology sphere link has universal abelian cover a Brieskorn complete intersection singularity. We describe a broad generalization: First, one has a class of complete intersection normal complex surface singularities called “splice type singularities,” which generalize Brieskorn complete intersections....
