Research Summary :
Algebraic Geometry is a fundamental area of Mathematics and has a long history. I have been working in this research field since 1980. The main research targets in this field are figures defined by algebraic equations, like lines, circles, parabola and curves of degree d in 2dimensional plane. However, research interests of Algebraic Geometry have been expanded to Complex Geometry, Singularity Theory, Arithmetic Geometry, Cryptography, Mathematical Physics, Integrable Systems and so on. After establishing the basic theory of schemes, cohomology and many other technical developments, Algebraic Geometry can be applied to the many other areas and obtained much flexibility to attack many problems in mathematics, physics and other areas in science and technology. My research interests can be listed up in the following areas:
Hodge theory, KodairaSpencer deformation theory, Mirror symmetry conjecture, Geometry of Painlevé equations, Moduli theoretic approach for RiemmanHilbert correspondences.
