Yamagami, Atsushi:COE Researcher,Algebra,Fiscal Year 2003
- deformation theory of Galois representations, modular forms and Hecke algebras
- Research Interest:
- Algebraic number theory
- Research Activities:
- The aim of my study is solving ``Gouvea's conjecture``
which says that for a residual modular Galois
representation, the universal deformation ring is
isomorphic to the universal modular deformation ring.
