A discrete conformality for polyhedral metrics on surfaces is introduced in this paper which generalizes
earlier work on the subject. It is shown that each polyhedral metric on a surface is discrete
conformal to a constant curvature polyhedral metric which is unique up to scaling. Furthermore, the
constant curvature metric can be found using a discrete Yamabe flow with surgery.
We study stable curves of arithmetic genus 2 which admit two morphisms of finite degree d, resp. (d,d′), onto smooth elliptic curves, with particular attention to the case d prime.
