Monodromy of real isolated singularities
Norbert A'Campo
For isolated complex hypersurface singularities with real defining equation we show the existence of a monodromy vector field such that complex conjugation intertwines the local mo…

Quadratic vanishing cycles, reduction curves and reduction of the monodromy group of plane curve singularities
Norbert A'Campo
The geometric monodromy of a plane curve singularity is a quasi-finite diffeomorphism. In this paper we locate the reduction curves of the geometric monodromy and the quadratic van…

A combinatorial property of generic immersions of curves
Norbert A'Campo
A divide is a relative generic immersion of a finite union of copies of the unit interval in the unit disk. A divide defines a classical link in the 3- sphere, which is a fibered l…
