AI总结:
本文构造了一个无边界的完备黎曼曲面,该曲面不包含任何使得其单纯1骨架准等距嵌入的三角剖分,且曲面的最短环长可任意大,回答了Georgakopoulos的问题。
摘要:
我们构造了一个完备的黎曼曲面Σ,该曲面不包含任何三角剖分G⊂Σ,使得G的1骨架G^(1)到Σ的包含映射是准等距映射。我们的构造是无边界的,具有任意大的最短环长,并且不存在任何嵌入的图G⊂Σ,使得G^(1)到Σ的包含映射是准等距映射。这回答了Georgakopoulos提出的问题。
英文摘要:
We construct a complete Riemannian surface $Σ$ that admits no triangulation $G\subset Σ$ such that the inclusion $G^{(1)} \hookrightarrow Σ$ is a quasi-isometry, where $G^{(1)}$ is the simplicial 1-skeleton of $G$. Our construction is without boundary, has arbitrarily large systole, and furthermore, there is no embedded graph $G\subsetΣ$ such that $G^{(1)} \hookrightarrow Σ$ is a quasi-isometry. This answers a question of Georgakopoulos.
