Arithmetic Zariski multiplets of irreducible plane curves
24 avril 2025 - 14:00Salle de séminaires IRMA
Multicanonically embedded surfaces in projective space give rise to irreducible branch curves via projection from generic axes. Building on our previous work, we transfer results from the moduli space of surfaces to equisingular strata of plane curves. For instance, the faithful action of the Galois group on the connected components of the moduli spaces of surfaces isogenous to a product, as established by Bauer, Catanese, and Grunewald, gives rise to many arithmetic Zariski multiplets. This is a joint work with M. Loenne.
