Computation-free presentation of the fundamental group of generic -torus curves
Enrique Artal Bartolo, Jose I. Cogolludo-Agustin, Jorge Ortigas-Galindo
In this note, we present a new method for computing fundamental groups of curve complements using a variation of the Zariski-Van Kampen method on general ruled surfaces. As an appl…
On the connection between fundamental groups and pencils with multiple fibers
Enrique Artal Bartolo, José Ignacio Cogolludo-Agustín
We present two results about the relationship between fundamental groups of quasiprojective manifolds and linear systems on a projectivization. We prove the existence of a plane cu…
Essential coordinate components of characteristic varieties
Enrique Artal Bartolo, Jorge Carmona Ruber, Jose Ignacio Cogolludo Agustin
In this note we give an algebraic and topological interpretation of essential coordinate components of characteristic varieties and illustrate their importance with an example.
