Characterization of the complex projective space by holomorphic vector fields.
Cohomology of Compact Hyperkähler Manifolds and its Applications.
Complex analytic construction of the Kuranishi Family on a normal strongly pseudo convex manifold with real dimension 5.
Contact geometry and CR-structures on spheres
A normal form for small CR-deformations of the standard CR-structure on the (2n+1)-sphere is presented. The space of normal forms is parameterized by a single function on the sphere. For n>1, the normal form is used to obtain explicit embeddings into . For n=1, the cohomological obstruction to embeddability is identified.
