Ricci-flat Deformations of Holomorphic Vector Bundles
Marco Kuehnel
In this paper we give a criterion for a deformation of a hermitian vector bundle to be Ricci-flat. As an application we show that on a Kähler manifold, every deformation of a vecto…
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 and their Kaehler cone II
Marco Kuehnel
We prove the rationality of the Kähler cone and the positivity of , if is a Calabi-Yau-threefold with and has an embedding into a ${\bb P}^n$-bundle over ${\bb…
Calabi-Yau-threefolds with Picard number and their Kaehler cone I
Marco Kuehnel
We describe properties of the Kähler cone of general Calabi-Yau-threefolds with Picard number and prove the rationality of the Kähler cone, if is a Calabi-Yau-hypersur…
