Numerical Criteria for vey Ampleness of Divisors on Projective Bundles over an elliptic curve

Alberto Alzati, Marina Bertolini, Gian Mario Besana

In Butler, J.Differential Geom. 39 (1):1--34,1994, the author gives a sufficient condition for a line bundle associated with a divisor D to be normally generated on $X=P(E)$ where…
