On the range of the Radon transform on \(\mathbb Z^n\) and the related Volberg's uncertainty principle (Q1728856)

Summary: We characterize the image of exponential type functions under the discrete Radon transform \(R\) on the lattice \(\mathbb Z^n\) of the Euclidean space \(\mathbb R^n\) (\(n\geq 2\)). We also establish the generalization of Volberg's uncertainty principle on \(\mathbb Z^n\), which is proved by means of this characterization. The techniques of which we make use essentially in this paper are those of the Diophantine integral geometry as well as the Fourier analysis.
