Scrolls over four dimensional varieties
Tironi, Andrea Luigi
We point out the relations between the classical and the adjunction-theoretic definition of scroll over varieties of dimension four. In particular, we prove that an adjunction-theoretic scroll of dimension greater than or equal to seven, polarized by a very ample line bundle, is also a classical scroll and that a classical scroll is an adjunction-theoretic scroll with a few exceptions.
