Abstract:
We prove that there are only finitely many families of codimension two nonsingular subvarieties of quadrics $mathcal {Q}^{n}$ which are not of general type, for $n=5$ and $ngeq 7$. We prove a similar statement also for the case of higher codimension.

Keywords:Codimension two   Grassmannians   lifting   low codimension   not of general type   polynomial bound   quadrics
