A construction of generalized elliptic curves from twisted curves
arXiv:1411.1954
Abstract
We introduce a procedure for constructing a generalized elliptic curve from a genus-one twisted curve, and we use this procedure to define an explicit, modular isomorphism between two compactifications of moduli stacks of elliptic curves with level structure.
