Abstract

Let ℤ n be the lattice in ℝ n and G the set of all discrete hyperplanes in ℤ n. Similarly, as in the Euclidean case, for a function f on ℤ n, the discrete Radon transform Rf is defined by the integral of f over discrete hyperplanes, and R maps functions on ℤ n to functions on G. In this paper, we determine the Radon transform images of the Schwartz space S(ℤ n), the space of compactly supported functions on ℤ , and a discrete Hardy space H 1(ℤ n).
