Research Field : Algebraic Number Theory: Number theory for prehomogeneous vector spaces of parabolic type and their zeta functions

Research Summary : In number theory, we often encounter "zeta functions" which are complex analytic functions, and it becomes important to understand their analytic properties. "Prehomogeneous vector space (PV)" is one of the sources for producing such zeta functions. In particular, so called parabolic type PV has rich mathematical structures, and is regarded as important for a number of research areas, including number theory. Currently, I am working on those parabolic type PVs, with applications to number theory, and finding relations to related research areas.
