关于曲线对称积的重言式丛的判别式

Discriminant of Tautological Bundles on Symmetric Products of Curves

Andreas Krug

摘要:

计算了复光滑射影曲线的重言丛关于对称幂的判别式。由此可见,Bogomolov不等式并没有对重言丛的稳定性给出新的限制。它只排除重言式丛,这些重言式丛已知具有作为不稳定子丛的结构层。

英文摘要:

We compute a formula for the discriminant of tautological bundles on symmetric powers of a complex smooth projective curve. It follows that the Bogomolov inequality does not give a new restriction to stability of these tautological bundles. It only rules out tautological bundles which are already known to have the structure sheaf as a destabilising subbundle.
