摘要:

本文利用第二内蕴体积,在可分实Hilbert空间中Gaussian有界凸体的位似类空间上定义了一个度量。借助双曲型核,可推出该空间等距嵌入到一个无限维实双曲空间中。应用Malliavin calculus,能够将积分几何适配于无限维凸体。此外,我们给出了计算凸体第二内蕴体积的新公式,并描述了维度至少为二的Gaussian有界凸体双曲嵌入的完备化,从而回答了Debin和Fillastre [DF22]提出的问题。

英文摘要:

In this article, we use the second intrinsic volume to define a metric on the space of homothetic classes of Gaussian bounded convex bodies in a separable real Hilbert space. Using kernels of hyperbolic type, we can deduce that this space is isometrically embedded into an infinite-dimensional real hyperbolic space. Applying Malliavin calculus, it is possible to adapt integral geometry for convex bodies in infinite dimensions. Moreover, we give a new formula for computing second intrinsic volumes of convex bodies and offer a description of the completion for the hyperbolic embedding of Gaussian bounded convex bodies with dimension at least two and thus answer a question asked by Debin and Fillastre [DF22].
