摘要:
对于极化 Kähler 流形上的全纯向量丛 $E$,我们通过定义 Fubini-Study 度量的 Quot-概形极限,建立了 $E$ 的斜率稳定性与 Donaldson 泛函渐近行为之间的直接联系。特别地,我们给出了一个显式估计,证明了若 $E$ 是斜率稳定的,则 Donaldson 泛函在 Fubini-Study 度量集合上是强制的,并给出了 Hermitian-Einstein 度量蕴含斜率稳定性的一个新证明。
英文摘要:
For a holomorphic vector bundle $E$ over a polarised Kähler manifold, we establish a direct link between the slope stability of $E$ and the asymptotic behaviour of Donaldson's functional, by defining the Quot-scheme limit of Fubini-Study metrics. In particular, we provide an explicit estimate which proves that Donaldson's functional is coercive on the set of Fubini-Study metrics if $E$ is slope stable, and give a new proof of Hermitian-Einstein metrics implying slope stability.
