度量测度空间上的等周不等式与带可加误差的Lipschitz序
Isoperimetric inequality on a metric measure space and Lipschitz order with an additive error
摘要:
M. Gromov在度量测度空间的集合上引入了Lipschitz序关系,发展了丰富的理论。特别是,他声称,一个等周不等式上的非离散空间表示使用Lipschitz秩序。我们放宽了Lipschitz序的定义,允许一个加性误差与离散空间上的一个等周不等式有关。作为应用,我们利用离散$l^1$-立方体的一个等周不等式的极限,得到了非离散$n$ -维$l^1$-立方体的一个等周不等式.
英文摘要:
M. Gromov introduced the Lipschitz order relation on the set of metric measure spaces and developed a rich theory. In particular, he claimed that an isoperimetric inequality on a non-discrete space is represented by using the Lipschitz order. We relax the definition of the Lipschitz order allowing an additive error to relate with an isoperimetric inequality on a discrete space. As an application, we obtain an isoperimetric inequality on the non-discrete $n$-dimensional $l^1$-cube by taking the limits of an isoperimetric inequality of the discrete $l^1$-cubes.
