character表上的伽罗瓦作用
The Galois action on character tables
摘要:
给出了有限群特征标表上伽罗瓦作用的几何解释和推广。对每个有限群G,其推广为空间Map_G(G^n,\bar{Q})/S_n上的Galois作用,其中G通过同时共轭作用于n元组G^n,而对称群S_n置换这些分量.
英文摘要:
A geometric interpretation and generalisation for the Galois action on finite group character tables is sketched. The generalisation is a Galois action on the space Map_G(G^n,\bar{Q})/S_n for each finite G, where G acts by simultaneous conjugation on the n-tuples G^n and the symmetric group S_n permutes the components.
