On the structure of ideal class groups of CM-fields.
Some remarks on conjectures about cyclotomic fields and -groups of
On two types of complete discrete valuation fields
Abelian extensions of an absolutely unramified local field with general residue field.
On the structure of Milnor -groups of certain complete discrete valuation fields
For a typical example of a complete discrete valuation field of type II in the sense of [], we determine the graded quotients for all . In the Appendix, we describe the Milnor -groups of a certain local ring by using differential modules, which are related to the theory of syntomic cohomology.
Remarks on the λₚ-invariants of cyclic fields of degree p
On the ideal class groups of the maximal real subfields of number fields with all roots of unity
In this paper, for a totally real number field we show the ideal class group of is trivial. We also study the -component of the ideal class group of the cyclotomic -extension.
