| Outline of Final Research Achievements |
We obtain many results on relations between geometry of solvmanifolds and deformations of complex structures. In particular, we obtain counterexamples for closedness of Hodge decomposition. Moreover, we obtain many results on the Hodge theory of local system cohomology. In view of Kahler geometry, these results are surprising. Non-Kahler geometry had not been studied very much. By these results, we can give interests in Non-Kahler geometry.
