| Outline of Final Research Achievements |
The main purpose of this research is a contribution to Iwasawa theory from a view point of arithmetic topology. The main objects are the structural invariants of Galois groups of number fields with restricted ramification. This research provided various description of the nonabelian structure of pro-p Galois groups. In particular when the ramification at p is restricted cyclotomically, some invariants in Iwasawa theory were computed from the nonabelian structure of the Galois groups which are described as analogues of link groups.
