对于有限群G和域k,我们称k上的G-伽罗瓦扩展为G/k扩展。G/k扩展是否存在是反伽罗瓦问题的第一个版本。特别是k = Q的有理数域,在Q的绝对伽罗瓦群的研究中起着重要的作用。许多数学家已经证明了许多有限群G的G/Q扩展的存在性(如Malle-Matzat [14], Serre[19]等)。
For a finite group G and a field k,we call a G-Galois extension over k by G/k-extension. Whether a G/k-extension exists or not is the first version of inverse Galois problem. Especially the case when k = Q the rational number field, plays an important role in the study of the absolute Galois Group of Q. By many mathematicians, the existence of G/Q-extensions has been shown for a lot of finite groups G by now (cf. Malle-Matzat [14], Serre [19], etc.)
