| Outline of Final Research Achievements |
We studied mirror symmetry for K3 surfaces over finite fields and number fields, and aimed to refine their mirror-symmetric properties from arithmetic viewpoints. The K3 surfaces we considered are algebraic surfaces in weighted projective 3-spaces with non-symplectic involution and defined by the equations of Delsarte type or by one-dimensional deformations of them. For such K3 surfaces, we computed the height of their formal Brauer groups and refined mirror symmetry for K3 surfaces using the height of formal groups. We then observed mirror symmetry among the zeta-functions of such K3 surfaces and also in their special values described in terms of Jacobi sums etc. Furthermore, we showed the modularity of L-functions of the K3 surfaces we considered.
