An introduction to the theory of elliptic curves the discrete logarithm problem fix a group g and an element g 2 g. However, whereas universal tricanonically embedded stable curves are easy to construct via hilbert schemes, we need to do additional work in the case of generalized elliptic curves because the group law involves the possibly nonproper smooth locus.
