我们研究了至少有一些锥角大于$2\pi$的球锥度量的变形。我们通过合成几何表明,在本说明中,对于一个家庭的这样的度量,有局部刚性的锥位置的选择,如果角度是固定的。这提供了一个证据的分析障碍考虑在最近的作品Mazzeo和作者。
We study the deformation of spherical conical metrics with at least some of the cone angles larger than $2\pi$. We show in this note via synthetic geometry that for one family of such metrics, there is local rigidity in the choice of cone positions if angles are fixed. This gives an evidence of the analytic obstruction considered in recent works of Mazzeo and author.
