带边三维流形上广义瑟斯顿球面堆积的刚性

Rigidity of generalized Thurston's sphere packings on 3-dimensional manifolds with boundary

Xu Xu, Chao Zheng

AI总结:

本文在带边三维流形上引入广义瑟斯顿球面堆积,证明其由组合标量曲率局部确定,并进一步证明在固定组合里奇曲率时具有无穷小刚性。

摘要:

受Guo-Luo在带边曲面上的广义圆堆积的启发,我们引入了带边三维流形上的广义瑟斯顿球面堆积。然后我们研究了广义瑟斯顿球面堆积的刚性。我们证明了广义瑟斯顿球面堆积由组合标量曲率局部确定。我们进一步证明了无穷小刚性,即广义瑟斯顿球面堆积在保持组合里奇曲率固定时不能被形变。

英文摘要:

Motivated by Guo-Luo's generalized circle packings on surfaces with boundary \cite{GL2}, we introduce the generalized Thurston's sphere packings on 3-dimensional manifolds with boundary. Then we investigate the rigidity of the generalized Thurston's sphere packings. We prove that the generalized Thurston's sphere packings are locally determined by the combinatorial scalar curvatures. We further prove the infinitesimal rigidity that the generalized Thurston's sphere packings can not be deformed while keeping the combinatorial Ricci curvatures fixed.
