Linear systems representing threefolds which are scrolls on a rational surface

Emilia Mezzetti, Dario Portelli

Published 1998-11-12Version 1

Let X be a scroll over a rational surface. We construct a linear system of surfaces in P^3 yielding a birational map from P^3 to X. We apply this construction to the scrolls of Bordiga and Palatini.
