正组合曲率带边有限图的分类
Classification of positive combinatorial curvature finite graphs with boundary

研究正组合曲率带边有限图的分类，证明除正多边形外，带边有限图只有71种互不同构的类型，并给出全部分类. 另外，得到正组合曲率有限图的最大顶点数为28.
We investigate the classification of positive combinatorial curvature finite graphs with boundary and prove that except the polygon case，such finite graphs with boundary has only 71 different cases. Furthermore，we prove that the maximal number of vertex is 28
