Global deformations of certain rational almost homogeneous projective bundles

Florian Schrack

We study global deformations of certain projective bundles over projective spaces. We show that any projective global deformation of a projective bundle over $\bP^1$ carries the st…

Extremal contractions of 2-Fano fourfolds

Florian Schrack

We consider extremal contractions on smooth Fano fourfolds whose second Chern character is positive. We show that such contractions can neither be of fiber type nor contract a divi…

Contact Kaehler Manifolds: Symmetries and Deformations

Thomas Peternell, Florian Schrack

We study complex compact Kaehler manifolds $X$ carrying a contact structure. If $X$ is almost homogeneous and $b_{2} (X) \geq 2$ , then $X$ is a projectivised tangent bundle (this was…

Algebraic approximation of Kähler threefolds

Florian Schrack

In the present work, we investigate existence of deformations and algebraic approximability for certain uniruled Kähler threefolds. In the first part, we establish existence of inf…
