关于单位生成的整数环

On rings of integers generated by their units

Christopher Frei

摘要:

我们肯定地回答了Jarden和Narkiewicz的问题:是否每个数域都有一个有限扩张L,使得L的整数环由它的单位生成(作为环)?作为证明的一部分,我们推广了Hinz关于数域中多项式的幂自由值的一个定理。

英文摘要:

We give an affirmative answer to the following question by Jarden and Narkiewicz: Is it true that every number field has a finite extension L such that the ring of integers of L is generated by its units (as a ring)? As a part of the proof, we generalize a theorem by Hinz on power-free values of polynomials in number fields.
