Clifford algebras, Fourier transforms, and quantum mechanics

H De Bie - Mathematical Methods in the Applied Sciences, 2012 - Wiley Online Library
In this review, we give an overview of several recent generalizations of the Fourier transform,
related to either the Lie algebra or the Lie superalgebra. In the former case, one obtains …

Pitt's inequalities and uncertainty principle for generalized Fourier transform
