Configurations of points and topology of real line arrangements
Benoît Guerville-Ballé, Juan Viu-Sos
A central question in the study of line arrangements in the complex projective plane is: when does the combinatorial data of the arrangement determine its topologic…

An arithmetic Zariski pair of line arrangements with non-isomorphic fundamental group
E. Artal, J. I. Cogolludo-Agustín, B. Guerville-Ballé +1
In a previous work, the third named author found a combinatorics of line arrangements whose realizations live in the cyclotomic group of the fifth roots of unity and such that thei…
