| Outline of Final Research Achievements |
Mirror symmetry of Calabi-Yau manifolds is a mysterious symmetry which has been found in the study of string theory in theoretical physics. Since its discovery, mirror symmetry has been studied in major institutes in the world. In this research, we have focused on Calabi-Yau manifolds which are called Reye congruence in the language of classical projective geometry. Finding a mirror Calabi-Yau manifold of Reye congruence Calabi-Yau manifold, and studying its deformation family, we have found that there appears another Calabi-Yau manifold which is paired with the Reye congruence. We have shown that this pair arises naturally from the projective duality. Furthermore, from a more modern viewpoint, we have shown that the two Calabi-Yau manifolds share an equivalent derived category of coherent sheaves. Interesting interplay between the projective duality and mirror symmetry has been appeared from this research.
