On bases of groups of circular units of some imaginary Abelian number fields

[摘要] Let k be an imaginary abelian number field whose conductor has at most two distinct prime divisors and whose maximal subfields which are ramified at one prime are imaginary. We shall find a basis for the group C of circular units in k and compute the index of C in the group E of units in k. (C) 1996 Academic Press, Inc.
