S-units and S-class group of first-degree cyclic number field

[摘要] In a cyclic number field K/Q of prime degree, we determine the Galois structure of S-units, for all Galois invariant finite set S of places of K. In particular, we study the links between this structure and that of the S-class group. (C) 2000 Academic Press.
