A Lower Bound on the Waist of Unit Spheres of Uniformly Convex Normed Spaces
摘要:
本文利用余维数大于1的局部化技巧和Borsuk-Ulam定理的一个强形式,给出了一致凸赋范空间单位球面束腰的一个下界.本文使用的工具遵循M. Gromov在[4]。我们的等周型不等式推广了[5]中的Gromov-Milman等周不等式.
英文摘要:
In this paper we give a lower bound on the waist of the unit sphere of a uniformly convex normed space by using the localization technique in codimension greater than one and a strong version of the Borsuk-Ulam theorem. The tools used in this paper follow ideas of M. Gromov in [4]. Our isoperimetric type inequality generalizes the Gromov-Milman isoperimetric inequality in [5].
