On generic singularities of intersections of ellipsoids: the octahedron
Enrique Artal Bartolo, Santiago López de Medrano, María Teresa Lozano
The goal of this work is to study the smoothings of singular coaxial intersections of ellipsoids (where coaxial includes concentric) with generic singularities, with special attent…
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…
Rational homology disk smoothings of surface singularities; the exceptional cases
Enrique Artal Bartolo, Jonathan Wahl
It is known (Stipsicz-Szabó-Wahl) that there are exactly three triply-infinite and seven singly-infinite families of weighted homogeneous normal surface singularities admitting a r…
On a quadratic form associated with a surface automorphism and its applications to Singularity Theory
Lilia Alanís-López, Enrique Artal Bartolo, Christian Bonatti +3
We study the nilpotent part of a pseudo-periodic automorphism of a real oriented surface with boundary . We associate a quadratic form defined on the first homology…
Torsion divisors of plane curves with maximal flexes and Zariski pairs
E. Artal Bartolo, S. Bannai, T. Shirane +1
There is a close relationship between the embedded topology of complex plane curves and the (group-theoretic) arithmetic of elliptic curves. In a recent paper, we studied the topol…
Module structure of the homology of right-angled Artin kernels
E. Artal Bartolo, J. I. Cogolludo-Agustín, S. López de Medrano +1
In this paper, we study the module structure of the homology of Artin kernels, i.e., kernels of non-resonant characters from right-angled Artin groups onto the integer numbers, the…
