曲面上两点Hilbert格式重言式丛的稳定性

Stability of tautological bundles on the Hilbert scheme of two points on a surface

Malte Wandel

摘要:

设(X,H)是满足H^1(X,O_X)=0的极化光滑射影曲面,F是X上的秩1无挠层或秩2 μ H-稳定向量丛.假设c_1(F)/=0。本文证明了Hilbert平方X^{[2]}上与F相关联的秩2和秩4重言式层F^{[2]}对某个极化是μ-稳定的。

英文摘要:

Let (X,H) be a polarized smooth projective surface satisfying H^1(X,O_X)=0 and let F be either a rank one torsion-free sheaf or a rank two μH-stable vector bundle on X. Assume that c_1(F)/=0. In this article it is shown that the rank two, respectively rank four tautological sheaf F^{[2]} associated with F on the Hilbert square X^{[2]} is μ-stable with respect to a certain polarization.
