| Outline of Final Research Achievements |
I studied Iwasawa theory for positively ramified extensions. The aims were: (a) to clarify properties of the "p-adic L-function" corresponding to the Galois group X of the maximal abelian pro-p extension which is p-ramified and positively ramified at p over a field of Z_p-extension, (b) to prove properties of X without "mu=0" assumption, and (c) to find more fine structures of X.
For (a), I obtained a result on certain functional equation of the "p-adic L function" when the base field is an abelian extension of an imaginary quadratic field, which I am preparing for publication. For (b), I had "a part of" functional equation of X for more general base field. For (c), I could not have enough progress and will continue my investigation.
