矩阵辐角函数的Radon变换

The Radon transform of functions of matrix argument

E. Ournycheva, B. Rubin

摘要:

该专着包含了一个系统的治疗一个循环的问题,在分析和积分几何有关反演的拉冬变换空间的真正的矩形矩阵。该变换将矩阵空间上的函数$f$在所谓的矩阵平面(由相应的矩阵方程确定的线性流形)上的积分赋予$f$。讨论了不同的反演方法。它们依赖于Radon变换、傅里叶变换、Garding-Gindikin分数次积分和里斯位势的矩阵修正之间的密切联系。一个特别强调的是新的更高的秩的现象,特别是,在可能的最小条件下,拉冬变换是明确定义的,可以明确地反转。除了Schwartz函数空间外,我们还利用了$L^p$ -空间和连续函数空间。将$R^n$上Radon变换的许多经典结果推广到高阶情形。

英文摘要:

The monograph contains a systematic treatment of a circle of problems in analysis and integral geometry related to inversion of the Radon transform on the space of real rectangular matrices. This transform assigns to a function $f$ on the matrix space the integrals of $f$ over the so-called matrix planes, the linear manifolds determined by the corresponding matrix equations. Different inversion methods are discussed. They rely on close connection between the Radon transform, the Fourier transform, the Garding-Gindikin fractional integrals, and matrix modifications of the Riesz potentials. A special emphasis is made on new higher rank phenomena, in particular, on possibly minimal conditions under which the Radon transform is well defined and can be explicitly inverted. Apart of the space of Schwartz functions, we also employ $L^p$-spaces and the space of continuous functions. Many classical results for the Radon transform on $R^n$ are generalized to the higher rank case.
