Dihedral coverings of trigonal curves

Algebraic Geometry 2013-06-17 v1

Abstract

We classify and study trigonal curves in Hirzebruch surfaces admitting dihedral Galois coverings. As a consequence, we obtain certain restrictions on the fundamental group of a plane curve~DD with a singular point of multiplicity (degD3)(\deg D-3).
