Published Papers

 
Takashi Hara and Tadashi Ochiai
Kyoto Journal of Mathematics   58(1) 1-100   Mar 2018   [Refereed]
We deduce the cyclotomic Iwasawa main conjecture for Hilbert modular cusp forms with complex multiplication from the multivariable main conjecture for CM number fields. To this end, we study in detail the behavior of the Tex-adic Tex-functions and...

Duke Mathematical Journal   158(2) 247-305   May 2011   [Refereed]
We construct the p-adic zeta function for a one-dimensional (as a Tex-adic Lie extension) non-commutative Tex-extension of a totally real number field such that the finite part of its Galois group is a pgroup with exponent Tex. We first calculate ...

Journal of Number Theory   130(4) 1068-1097   Mar 2008   [Refereed]
In this paper, we prove the Iwasawa main conjecture of totally real fields
for certain specific non-commutative Tex-adic Lie extensions, using the
integral logarithms introduced by Oliver and Taylor. Our result gives certain
generalization of Kazu...
