Trigonal curves and monodromy - III
Alexander Degtyarev
Bilkent University, Turkey
Özet : We continue the description of the braid monodromy of a trigonal curve and its relation to the dessin. The principal result is the fact that the monodromy group is a subgroup of genus zero. As an immediate application, we will discuss the dihedral coverings ramified at trigonal curves (equivalently, torsion of the Mordell—Weil group of an elliptic surface) and a trigonal curve version of the so-called Oka conjecture.
