Deconvolution for the Pompeiu Problem on the Heisenberg Group, I

Conference paper
Part of the Springer Proceedings in Mathematics book series (PROM, volume 16)


We consider variations on the Pompeiu transform for the Heisenberg group H n and focus on cases where the transform is known to be injective; in particular the cases of averages over a sphere and a ball, or two balls of appropriate radii. In these cases we develop a method which provides for the reconstruction of the function f from its integrals.

In addition, we consider these issues in connection with the Weyl calculus and group Fourier transform. We furthermore explore issues of convergence for this method of deconvolution and related issues of size of the Gelfand transform near the zero sets. Finally, given a set of deconvolvers which work for Euclidean space C n , we consider the problem of how to extend the deconvolution to the Heisenberg group, and we provide the extension in special cases.
