论文摘要
对于每一个整数$ a \ geq 2 $,我们将加权投影空间中的Hypersurfaces的K稳定性与$ 2A $ 2A $的二元形式的二元形式的git稳定性相关联$ \ mathbb {p}(1,1,a,a,a,a)$ 2a $。此外,我们证明,如果它是准平滑的,那么这种超表面是k-polystable,而不是k-stable。
For every integer $a \geq 2$, we relate the K-stability of hypersurfaces in the weighted projective space $\mathbb{P}(1,1,a,a)$ of degree $2a$ with the GIT stability of binary forms of degree $2a$. Moreover, we prove that such a hypersurface is K-polystable and not K-stable if it is quasi-smooth.
