设G是S ~(14)的可迁子群.对于任意域k,设G自然地作用于由定义的有理函数域k-自同构,我们将证明当G是初等交换2-群的扩张时,G的不动域的合理性。
LetGbe a transitive subgroup ofS14. For any fieldk, letGact naturally on the rational function fieldviak-automorphisms defined byfor anyandWe will show the rationality of the fixed fieldwhenGis an extension of an elementary abelian 2-group.
