有限子集外具有非负曲率的图、调和函数和端数

Graphs with nonnegative curvature outside a finite subset, harmonic functions and number of ends

Bobo Hua, Florentin Münch

摘要:

研究了在有限子集外具有非负Bakry-Émery曲率或Ollivier曲率的图。对于这样的图,通过引入离散的格罗莫夫-豪斯多夫收敛性,我们证明了有界调和函数空间是有限维的,作为推论,非抛物端点的个数是有限的.

英文摘要:

We study graphs with nonnegative Bakry-Émery curvature or Ollivier curvature outside a finite subset. For such a graph, via introducing the discrete Gromov-Hausdorff convergence we prove that the space of bounded harmonic functions is finite dimensional, and as a corollary the number of non-parabolic ends is finite.
