The Intersection Form of a Plane Isolated Line Singularity

The Intersection Form of a Plane Isolated Line Singularity

Consider an isolated singularity of a real analytic function in two variables. There exists a method to calculate its intersection matrix based on consideration of a real level of some special perturbation of the function [3]. In this paper we extend this method to the case of functions with a smoot...

Zusammenfassung:Consider an isolated singularity of a real analytic function in two variables. There exists a method to calculate its intersection matrix based on consideration of a real level of some special perturbation of the function [3]. In this paper we extend this method to the case of functions with a smooth curve as a singular set.
