## Abstract Consider the Poincare unit disk model for the hyperbolic plane **H**^2^. Let Ξ be the set of all horocycles in **H**^2^ parametrized by (__ΞΈ, p__), where __e^iΞΈ^__ is the point where a horocycle __ΞΎ__ is tangent to the boundary |__z__| = 1, and __p__ is the hyperbolic distance from __ΞΎ_

## Abstract In this paper, we study the inversion formula for recovering a function from its windowed Fourier transform. We give a rigorous proof for an inversion formula which is known in engineering. We show that the integral involved in the formula is convergent almost everywhere on \documentcla
The present paper deals with the computational complexity of the discrete inverse problem of reconstructing ΓΏnite point sets and more general functionals with ΓΏnite support that are accessible only through some of the values of their discrete Radon transform. It turns out that this task behaves quit
