Research Abstract

In this research project, I have obtained results on (1) a formula describing Z_p-rank of tamely ramified Iwasawa modules of the basic Z_p-extension, (2) an analogy of Weil paring for ideal class groups of number fields, (3) the isomorphism classes of Galois cohomology groups of global unit groups, and (4) a characterization of the Dedekind zeta functions in terms of a family of the Galois groups of restricted ramified extensions.
