Clifford代数、傅立叶变换和量子力学

Clifford algebras, Fourier transforms and quantum mechanics

Hendrik De Bie

摘要:

本文综述了近年来傅里叶变换的几种推广,它们与李代数sl_2或李超代数osp(1)有关|2)。在前一种情况下,人们得到傅立叶变换的标量推广,包括分数傅立叶变换、Dunkl变换、径向变形傅立叶变换和超傅立叶变换。在后一种情况下,必须使用Clifford分析的框架,并得到Clifford-Fourier变换和径向变形的超复数Fourier变换。本文对这些变换作了详细的阐述,着重讨论了变换的本征函数和谱、积分核的特征以及与各种特殊函数的联系等问题。

英文摘要:

In this review, an overview is given of several recent generalizations of the Fourier transform, related to either the Lie algebra sl_2 or the Lie superalgebra osp(1|2). In the former case, one obtains scalar generalizations of the Fourier transform, including the fractional Fourier transform, the Dunkl transform, the radially deformed Fourier transform and the super Fourier transform. In the latter case, one has to use the framework of Clifford analysis and arrives at the Clifford-Fourier transform and the radially deformed hypercomplex Fourier transform. A detailed exposition of all these transforms is given, with emphasis on aspects such as eigenfunctions and spectrum of the transform, characterization of the integral kernel and connection with various special functions.
