Research Keyword Number Theory, Iwasawa Theory
Research Area Algebra (Number theory, Iwasawa theory, elliptic curves, Selmer groups, p-adic Lie extensions)
Research Institute Theme It is believed that there exist mysterious relations between two quite differnt invariants, Selmer groups and L-functions, which are both attached to algebraic number fields or elliptic curves. Iwasawa theory studies generalizations and "p-adic" refinements of these relationships by considering these invariants over some big Galois extensions. Currently, I am studying "Noncommutative Iwasawa theory" and "Iwasawa theory for Galois representations" which are attempts to generalize the classical framework of Iwasawa theory.
