Applications of the Eisenbud-Levine’s theorem to real algebraic geometry

  • Conference paper

Part of the book series: Progress in Mathematics ((PM,volume 109))

Abstract

Let f: (R n,0) → (R p,0) be the germ of an analytic mapping. The fibre f - 1(0) is locally homeomorphic to a cone, with vertex 0. The base L of the cone is the intersection of f 1(0) with a small sphere S centred at 0. Investigation of topology of L is one of the most crucial aims of singularity theory.
