Hi Andreas, congratulations for finishing/uploading your first arakelov paper. I skimed through and it looks interesting, but unfortunately I cant say much more than that :) As a student of Oliver I just wondered about two things: 1. Is the order Röndigs, Spitzweck, Ostvaer correct? That might have something to do with Ostvaers crazy O. 2. That cited result does not appear in the references, right?
