Twisted Alexander polynomials of Plane Algebraic Curves
Jose Ignacio Cogolludo, Vincent Florens
We consider the Alexander polynomial of a plane algebraic curve twisted by a linear representation. We show that it divides the product of the polynomials of the singularity links,…

Fundamental Group for some Cuspidal Curves
Jose Ignacio Cogolludo
We construct a family of plane curves as pull-backs of a conic for abelian coverings of P^2. If the conic is tangent to the ramification lines one obtains a family of curves of deg…
