具有充分正规丛、代数性和圈锥的紧子簇

Compact subvarieties with ample normal bundles, algebraicity and cones of cycles

Thomas Peternell

摘要:

本文研究了紧致Kähler流形X中具有充足法丛的子流形(子簇)的两个特征。首先,我们研究代数X如何可能,即我们研究代数维数。其次,我们研究了在X是射影的情况下,具有丰富法丛的曲线。我们证明在各种情况下,类的曲线是在内部的森锥。

英文摘要:

In this note we study two features of submanifolds (subvarieties) with ample normal bundles in a compact Kähler manifold X. First, we study how algebraic X can be, i.e. we investigate the algebraic dimension. Second, we study curves with ample normal bundles in case X is projective. We prove in various cases that the class of the curve is in the interior of the Mori cone.
