| Outline of Final Research Achievements |
By introducing Iwasawa theoretic method to the study of the absolute Galois groups of number fields, I have succeeded in (1) generalizing the Neukirch-Uchida theorem to number fields of infinite degrees, (2) characterizing Dedekind zeta functions from small quotients of the absolute Galois groups, (3) establishing freeness conjecture for the imaginary quadratic fields.
