Class number relation between type (l,l/,…, l) function fields over F_q(T) and their subfields
【摘要】 <正> Let L/Fq(T) be a tame abelian extension of type (l, l,...l). The ratio of the degree zero divisor dass number (as well as the ideal class number) of L to the product of corresponding class numbers of all cydic subfields of L is clearly determined.
