摘要:

用优化的方法得到lnp空间中单位球位似意义下的Banach-Mazur距离.与Banach-Mazur距离相比,描述了两个凸体间未经任何旋转变换下的距离.此后,运用这一结果估计了lnp空间中单位球的高斯测度.

关键词: 高斯测度;lnp空间;Banach-Mazur 距离;渐近性质

Abstract:

The Banach-Mazur distance, defined by homothetic transformation, between two different unit balls in lnp-space is shown with optimization calculation. Compared to the Banach-Mazur distance, it shows distance between convex bodies without any rotation. The result is applied to estimate the Gaussian measure of unit balls in the lnp-space.

Key words: Gaussian measure;lnpspace; Banach-Mazur distance; asymptotic property
