不可定向曲面上曲线复形的超单射
Superinjective Simplicial Maps of the Complexes of Curves on Nonorientable Surfaces
摘要:
证明了紧致、连通、不可定向曲面的曲线复形的超内射单纯形映射是由曲面的同胚诱导的,如果满足$(g, n) \in \{(1, 0), (1, 1), (2, 0), (2, 1), (3, 0)\}$或$g + n \geq 5$,其中$g$是曲面的亏格,$n$是边界分支的个数.
英文摘要:
We prove that each superinjective simplicial map of the complex of curves of a compact, connected, nonorientable surface is induced by a homeomorphism of the surface, if $(g, n) \in \{(1, 0), (1, 1), (2, 0), (2, 1), (3, 0)\}$ or $g + n \geq 5$, where $g$ is the genus of the surface and $n$ is the number of the boundary components.
