Geometric Generalization of Gaussian Period Relations with Application to Noether's Problem for Meta-Cyclic Groups
Tokyo Journal of Mathematics
We study Noether's problem over Q for meta-cyclic groups. This paper is an extension of the previous work  , which was concerned with the cyclic group C n of order n. We shall give a simple description of the action of the normalizer of C n in S n to the function field Q(x 1 , • • • , x n ), in terms of the generators of the fixed field of C n given in  . Using this, we settle Noether's problem for the dihedral group of order 2n (n ≤ 6) and the Frobenius group of order 20 with explicitdoi:10.3836/tjm/1244208276 fatcat:br3bcxg4ivdslmmlj5dtm6eoxa
