关于Galois有理覆盖的注记

Remarks on Galois rational covers

Aleksandr V. Pukhlikov

摘要:

在这篇文章中,我们改进了作者最近证明的关于本原Fano簇$V$的伽罗瓦有理覆盖$X\dashrightarrow V$的定理,在两个方向上:我们将证明有效的伽罗瓦群$G$的类扩展到最大值,并放松了簇$V$必须满足的条件--仅正则性就足够了。

英文摘要:

In this note we improve the theorem on Galois rational covers $X\dashrightarrow V$ for primitive Fano varieties $V$, recently proven by the author, in the two directions: we extend to the maximum the class of Galois groups $G$, for which the proof works, and relax the conditions that must be satisfied by the variety $V$ -- the divisorial canonicity alone is sufficient.
