| Outline of Final Research Achievements |
In this research project, we obtain the followoing results: 1.A generalization of the Neukirch-Uchida Theorem to number fields of infinite degree, 2.Criterion of arithmetically equivalence in terms of Iwasawa modules with restricted ramification, 3. Criterion for commutativity of maximal unramified p-extensions
over Z_p-extension fields.
