Threefolds of order one in the six-quadric

Lev Borisov, Jeff Viaclovsky

Published 2008-08-03, updated 2008-08-12Version 2

Consider the smooth quadric Q_6 in P^7. The middle homology group H_6(Q_6,Z) is two-dimensional with a basis given by two classes of linear subspaces. We classify all threefolds of bidegree (1,p) inside Q_6.
