Outline of Final Research Achievements

In the 19th century, Gauss, Abel and Jacobi constructed the theory of elliptic curves and their moduli. It had a big influence in mathematics of 20th century. At present, it is developed to the higher dimensional analogues. The K3 surface is the 2-dimensional analogue of the elliptic curve.
On the other hand, Hilbert proposed his 12th problem in 1901, it was an important proposal in number theory. In 1960's, Shimura gave a big contribution for this problem. But the Hilbert 12th problem iself is still open. In our research project, we could give a visualization of Shimura's theory and constructed a series of explicit examples.
