We prove a conjecture of Lehmann and Tanimoto about the behaviour of the Fujita invariant (or -constant appearing in Manin’s conjecture) under pull-back to generically finite covers. As a consequence we obtain results about geometric consistency of Manin’s conjecture.

Manin 猜想和有限覆盖的 Fujita 不变量
我们证明了 Lehmann 和 Tanimoto 关于 Fujita 不变量(或 -常数出现在 Manin 的猜想中)在拉回到一般有限的覆盖。因此,我们获得了关于 Manin 猜想的几何一致性的结果。
