Contact Kähler Manifolds: Symmetries and Deformations
• Mathematics
• 2014
We study complex compact Kahler manifolds X carrying a contact structure. If X is almost homogeneous and b 2(X) ≥ 2, then X is a projectivised tangent bundle (this was known in the projective caseExpand
Submanifolds with ample normal bundles and a conjecture of Hartshorne
The Hartshorne conjecture predicts that two submanifolds X and Y in a projective manifold Z with ample normal bundles meets as soon as dim X + dim Y is at least dim Z. We mostly assume slightlyExpand
On the ample vector bundles over curves in positive characteristic
• Mathematics
• 2004
Abstract Let E be an ample vector bundle over a smooth projective curve defined over an algebraically closed field of positive characteristic. We construct a family of curves in the total space of EExpand
How to Use Cycle Space in Complex Geometry
In complex geometry, the use of n-convexity and the use of ampleness of the normal bundle of a d-codimensional submanifold are quite difficult for n > 0 and d > 1. The aim of this paper is to explainExpand
