Recently G. Anderson introduced an explicit Galois module A that is closely related to the ideal class group of a cyclotomic field. We study A for a cyclotomic field L of prime conductor. We prove that A has the same Tate cohomology groups as the ideal class group of L and we show that the dual of A

Let `be a primitive 2 m th root of unity. We prove that Z[:]=Z [`] if and only if :=n\`i for some n, i # Z, i odd. This is the first example of number fields of arbitrarily large degree for which all power bases for the ring of integers are known. 2001 Academic Press ## 1. Introduction A number f
We introduce a generalized Demjanenko matrix associated with an arbitrary abelian field of odd prime power conductor, and exhibit direct connections between this matrix and both the relative class number and the cyclotomic units of the field. Beyond using the analytic class number formula, all argum
In this paper, we determine all finite separable imaginary extensions KΓF q (x) whose maximal order is a principal ideal domain in case KΓF q (x) is a non zero genus cyclic extension of prime power degree. There exist exactly 42 such extensions, among which 7 are non isomorphic over F q . 2000 Acad
