Local invariants on quotient singularities and a genus formula for weighted plane curves
Jose Ignacio Cogolludo-Agustin, Jorge Martin-Morales, Jorge Ortigas-Galindo
In this paper we extend the concept of Milnor fiber and Milnor number of a curve singularity allowing the ambient space to be a quotient surface singularity. A generalization of th…
Orbifold groups, quasi-projectivity and covers
Enrique Artal Bartolo, Jose Ignacio Cogolludo-Agustin, Daniel Matei
We discuss properties of complex algebraic orbifold groups, their characteristic varieties, and their abelian covers. In particular, we deal with the question of (quasi)-projectivi…
Quasi-projectivity, Artin-Tits Groups, and Pencil Maps
Enrique Artal Bartolo, Jose Ignacio Cogolludo-Agustin, Daniel Matei
We consider the problem of deciding if a group is the fundamental group of a smooth connected complex quasi-projective (or projective) variety using Alexander-based invariants. In…
