Let F be a totally real number field of odd degree. We prove several purely local criteria for the asymptotic Fermat's Last Theorem to hold over F and also, for the nonexistence of solutions to the unit equation over F. For example, if two totally ramifies and three splits completely in F, then the asymptotic Fermat's Last Theorem holds over F.
设 F 为奇数次的实完全数域。我们证明了若干纯粹局部的条件,使得 Fermat 最后定理在 F 上成立,同时也使得 F 上单位方程无解。例如,如果两个分支完全分支,三个完全分裂,那么渐近 Fermat 最后定理在 F 上成立。
