Let X be a ruled surface over C, that is a complete nonsingular surface with a surjective morphism π: X→C such that each fibre is isomorphic to P^1 and π admits a section. When C is an elliptic curve, X is called an elliptic ruled surface. From now on we consider elliptic ruled surfaces over a fixed elliptic curve C. The present paper is a continuation of [2], and our notations are the same as used in that paper.}, pages = {17--26}, title = {Projective Normality and the Defining Equations of an Elliptic Ruled Surface with Negative Invariant}, volume = {33}, year = {1982} }
