Torsion points on elliptic curves and tame semistable coverings

28 Feb 2018 Helminck P. A.

In this paper, we study tame Galois coverings of semistable models that arise from torsion points on elliptic curves. These coverings induce Galois morphisms of intersection graphs and we express the decomposition groups of the edges in terms of the reduction type of the elliptic curve... (read more)
