Let L / K be a finite Galois extension of fields with Galois group G . It is known that L / K admits exactly two Hopf–Galois structures when G is non‐abelian simple. In this paper, we extend this result to the case when G is quasisimple.

拟扩展Galois群在有限扩展上的Hopf–Galois结构

大号 / ķ 与Galois组成为字段的有限Galois扩展 G 。众所周知 大号 / ķ 在以下情况下,正好接受两个Hopf–Galois结构 G 非常简单。在本文中,我们将此结果扩展到以下情况: G 是quasisimple。
