唐纳森证明了:如果一个极化流形$(V,L)$在$c_1(L)$中具有常数量曲率K“ahler度量,并且它的自同构群Aut$(M,L)$是离散的,则$(V,L)$是渐近Chow稳定的.在本文中,我们将展示一个例子,这意味着上述结果不成立的情况下,Aut$(V,L)$是不离散的。
Donaldson proved that if a polarized manifold $(V,L)$ has constant scalar curvature K\"ahler metrics in $c_1(L)$ and its automorphism group Aut$(M,L)$ is discrete, $(V,L)$ is asymptotically Chow stable. In this paper, we shall show an example which implies that the above result does not hold in the case when Aut$(V,L)$ is not discrete.
