| Outline of Final Research Achievements |
Plectic conjecture by J. Nekovar and A. Scholl is considered to give a strong impact on the study for motive with real multiplication if the program is completed. However, the program has just started. We studied the Hodge realization of the plectic cohomology. We gave an equivalent description of mixed plectic Hodge structures in terms of the weight and partial Hodge filtrations. We also constructed an explicit complex calculating the extension groups in this category. This result is important to consider applications to concrete problems.
