广义Dehn函数Ⅰ

Generalized Dehn Functions I

Chad Groft

摘要:

设X是有限CW复形或紧Lipschitz邻域收缩核,且具有泛覆盖Z,M是维数至少为2且边界非空的紧可定向流形.我们建立了从M到Z的函数在度量和细胞意义上的等周轮廓的存在性,并证明了当X是三角化CLNR(例如三角化黎曼流形)时,它们等价于尺度因子。当X是高度连接的时候,这似乎是最有趣的,但这不是必需的。我们还表明,两个有限的复合物X和Y有相同的配置文件的缩放给定的存在下,它们之间的一个充分连接的映射。

英文摘要:

Let X be a finite CW complex or compact Lipschitz neighborhood retract with universal cover Z; let M be a compact orientable manifold of dimension at least 2 and nonempty boundary. We establish the existence of an isoperimetric profile for functions from M to Z, in the metric and cellular senses, and show that they are equivalent up to scaling factors when X is a triangulated CLNR (for example a triangulated Riemannian manifold). This seems to be most interesting when X is highly connected, but this is not required. We also show that two finite complexes X and Y have the same profiles up to scaling given the existence of a sufficiently connected map between them.
