局部Picard群的Lefschetz

Lefschetz for local Picard groups

Bhargav Bhatt, Aise Johan de Jong

摘要:

本文证明了Kollár关于局部Picard群的Grothendieck-Lefschetz超平面定理的一个加强。我们的方法,这依赖于无环性结果的绝对整闭包,也导致了一个限制定理的高秩丛的正特征的投射品种。

英文摘要:

We prove a strengthening of the Grothendieck-Lefschetz hyperplane theorem for local Picard groups conjectured by Kollár. Our approach, which relies on acyclicity results for absolute integral closures, also leads to a restriction theorem for higher rank bundles on projective varieties in positive characteristic.
