群与齐性空间上的扩散小波

Diffusive wavelets on groups and homogeneous spaces

Svend Ebert, Jens Wirth

摘要:

本论述的目的是解释基本思想背后的概念扩散小波领域的语言表示论的李群和框架内的组傅里叶变换的彼得-外尔分解$L^2(G)$的紧凑李群$G$。在发展了紧致群及其齐性空间的一般概念之后,我们给出了环面的具体例子--这反映了$R^n$的情况--以及球面$S^2$和$S^3$的情况。

英文摘要:

The aim of this exposition is to explain basic ideas behind the concept of diffusive wavelets on spheres in the language of representation theory of Lie groups and within the framework of the group Fourier transform given by Peter-Weyl decomposition of $L^2(G)$ for a compact Lie group $G$. After developing a general concept for compact groups and their homogeneous spaces we give concrete examples for tori -which reflect the situation on $R^n$- and for spheres $S^2$ and $S^3$.
