介绍了调和NA群上的Radon变换,以及这个变换和Helgason-Fourier变换之间的关系.基于这些变换,将实直线R上Morgan形式的Hardy不确定原理和Cowling-Price形式的Hardy不确定原理推广到调和NA群.
We generalize two versions of Hardy's uncertainty principles due to Morgan and Cowling-Price in the real line R to harmonic NA groups. To do so, we use the Radon transforms and its relation with the Helgason-Fourier transformations on the class of the groups .
