Query: A construction of generalized elliptic curves from twisted curves   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.
