我们按以下方式研究五次费马曲线 F(5) 的函数域 K 的结构:令 K m 为 K 的 g 最大有理子域。​​然后通过从 F(5) 到以 p 为中心的直线投影 ε F(5) 来获得域扩展 K/K m。利用这个事实,我们从几个角度考虑场扩展 K/K m。
We study the structure of the function field K of the quintic Fermat curve F(5) in the following way: Let K m be a g-maximal rational subfield of K. Then the field extension K/K m is obtained by the projection from F(5) to a line with a center p, ∈ F(5). By using this fact, we consider the field extension K/K m from several point of view.
