Outline of Final Research Achievements

In mixed case, we constructed spaces of SL(2)-orbits, fine moduli of log mixed Hodge structures. As geometric applications, we constructed Neron models and showed analyticity of the common zeros of sections of the Neron model. We also constructed a Neron model which accepts any given admissible normal function. As applications of these results to physics, we describe closed and open mirror symmetry for quantic 3-folds. All of these results are published.
In mixed case, supplementing spaces of nilpotent i-orbits with ratio structure and spaces of SL(2)-orbit with star, we completed an amplified fundamental diagram by which various limits of period maps and normal functions are compared. These results are submitted and available from arXiv.
