On invariance and Ricci-flatness of Hermitian metrics on open manifolds

Bert Koehler, Marco Kuehnel

We discuss a technique to construct Ricci-flat hermitian metrics on complements of (some) anticanonical divisors of almost homogeneous manifolds and discuss when this metric is com…

Calabi-Yau-threefolds with Picard number $ρ (X) = 2$ and their Kaehler cone II

Marco Kuehnel

We prove the rationality of the Kähler cone and the positivity of $c_{2} (X)$ , if $X$ is a Calabi-Yau-threefold with $ρ (X) = 2$ and has an embedding into a ${\bb P}^n$-bundle over ${\bb…

Calabi-Yau-threefolds with Picard number $ρ (X) = 2$ and their Kaehler cone I

Marco Kuehnel

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-hypersur…
