Trimester on Kaehler and related geometries

A special trimester on Kähler and related geometries will be held at Nantes University from september to december 2009. The topics of interest are

The trimester will consist of two events:

An international conference
Invitations for extended periods at Laboratoire Jean Leray throughout the trimester. Researchers are welcome to interact and to give mini lectures on their favorite topics.

Conference - november 9th - 13th 2009

Claire Voisin (IHES CNRS, 27/11/09)
- Geometry seminar: Algèbres de cohomologie des variétés kählériennes
Julien Keller (Université de Provence, 10/11/09-11/12/09)
- Three Lectures: Autour du théorème de Calabi-Yau - Cours 1 - Cours 2
Misha Verbitsky (02/11/09-13/11/09)
- Three lectures: on Sasakian manifolds and locally conformally Kaehler geometry
  1. Sasakian and CR-geometry
  2. Structure theorem Vaisman manifolds
  3. Embedding theorem for Sasakian manifolds
  Abstract: Sasakian manifolds are Riemannian manifolds equipped with an $\R$-equivariant Kaehler structure on their Riemannian cone. This allows one to characterize the Sasakian manifolds in terms of Kaehler structure on the corresponding cones. Three lectures are planned: 1. A characterization of Sasakian manifolds in terms of CR-geometry. 2. Locally conformally Kaehler geometry, Vaisman manifolds and the structure theorem, providing an equivalence of Vaisman geometry and Sasakian geometry. 3. A version of Kodaira theorem for Sasakian and Vaisman manifolds, giving a complex embedding of a Vaisman manifold into a Hopf manifold and a CR-embedding of a Sasakian manifold into a sphere. These results are obtained jointly with Liviu Ornea.

The seminar takes place every wednesday at 5pm at the Laboratoire Jean Leray.
