Ordinary --tuples in cyclic quotient surface singularities
José I. Cogolludo-Agustín, Tamás Lászlo, Jorge Martín-Morales +1
We describe those Weil divisors of cyclic quotient surface singularities which are (abstract) --tuple curve singularities.
On the topology of fiber-type curves: a Zariski pair of affine nodal curves
José Ignacio Cogolludo-Agustín, Eva Elduque
In this paper we explore conditions for a curve in a smooth projective surface to have a free product of cyclic groups as the fundamental group of its complement. It is known that…
Cyclic coverings of rational normal surfaces which are quotients of a product of curves
Enrique Artal Bartolo, José Ignacio Cogolludo-Agustín, Jorge Martín-Morales
This paper deals with cyclic covers of a large family of rational normal surfaces that can also be described as quotients of a product, where the factors are cyclic covers of algeb…
Quasi-projective varieties whose fundamental group is a free product of cyclic groups
José Ignacio Cogolludo-Agustín, Eva Elduque
In this work we study smooth complex quasi-projective surfaces whose fundamental group is a free product of cyclic groups. In particular, we prove the existence of an admissible ma…
Homology of even Artin kernels
Rubén Blasco-García, José Ignacio Cogolludo-Agustín, Conchita Martínez-Pérez
We explicitly compute the homology groups with coefficients in a field of characteristic zero of cocyclic subgroups or even Artin groups of FC-type. We also give some partial resul…
On the Sigma invariants of even Artin groups of FC-type
Ruben Blasco. García, Jose Ignacio Cogolludo-Agustín, Conchita Martínez-Pérez
In this paper we study Sigma invariants of even Artin groups of FC-type, extending some known results for right-angled Artin groups. In particular, we define a condition that we ca…
