关于Polya群的一个注记
A note on Polya groups
摘要:
设$K/\mathbf{Q}$是有限Galois扩张. $K$的波利亚群是类群$Cl(K)$的子群,由$K$的模糊理想类生成。本文证明了有限阿贝尔群同构于数域的Pólya群。
英文摘要:
Let $K/\mathbf{Q}$ be a finite Galois extension. The Pólya group of $K$ is the subgroup of the class group $Cl(K)$, generated by the classes of ambiguous ideals of $K$. In this note, among other results, we prove that every finite abelian group is isomorphic to the Pólya group of a number field.
