| dc.description | We describe properties of the Kähler cone of general Calabi-Yau-threefolds with Picard number $ρ(X)=2$ and prove the rationality of the Kähler cone, if $X$ is a Calabi-Yau-hypersurface in a ${\mathbb P}^2$-bundle over ${\mathbb P}^2$ and $c_3(X)\le -54$. Without the latter assumption we prove the positivity of $c_2(X)$. | |
