| Outline of Final Research Achievements |
In the field of Complex Geometry "Kaehler structure" is a central subject. As a study of locally conformally Kaehler structures (LCK structure for short) we have shown that a compact homogeneous LCK manifold is a holomorphic fibre bundle over a flag manifold with fiber a 1-complex torus. Furthermore, we have shown that they are all of Vaisman type, that is, its associated Lee form is parallel with respect to the Riemann metric.
As an important research activity during the period of this research project we have organised the international symposium "Complex Geometry and Lie Groups" in Torino, June 16-20, 2015 and in Nara, March 22-26, 2016.
