CYCLOTOMIC UNITS AND DIVISIBILITY OF THE CLASS NUMBER OF FUNCTION FIELDS Ahn, Jae-Hyun; Jung, Hwan-Yup;
Let ＝(T) be a rational function field. Let be a prime number with (, q-1) ＝ 1. Let K/ be an elmentary abelian -extension which is contained in some cyclotomic function field. In this paper, we study the -divisibility of ideal class number of K by using cyclotomic units.s.s.
