Abstract
The author obtained an explicit 2-rank formula for the ideal class groups of quadratic function fields and also get a lower bound for the l-rank of the ideal class groups of l-th Kummer function fields.Consequently,the author determined all l-th Kummer function fields whose ideal class numbers are prime to l.It′s also proved that if the l-Sylow subgroup of the ideal class group of a l-th Kummer function field is cyclic then it must be of order l.关键词
