Abstract

We establish injectivity results for three different spherical means on an H-type group, G. The first one is the standard spherical mean operator, which is defined as the average of a function over the spheres in the complement of the center, the second one is the average over the product of spheres in the center and its complement, and the third one is the average over the spheres defined by a homogeneous norm on G. If m is the dimension of the center of G, injectivity of these spherical means is proved for the range 1�p�2mm-1. Examples are provided to show the sharpness of our results in the first two cases. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.
