Consider the Poincare unit disk model for the hyperbolic plane H-2. Let Xi be the set of all horocycles in H 2 parametrized by (theta, p), where e(i theta) is the point where a horocycle xi is tangent to the boundary vertical bar z vertical bar = 1, and p is the hyperbolic distance from xi to the origin. In this paper we invert the dual Radon transform R* : mu(theta, p) -> mu(z) under the assumption of exponential decay of mu and some of its derivatives. The additional assumption is that P-m(d/dp) (mu(m)(p)e(p)) be even for all m is an element of Z. Here P-m (d/dp) is a family of differential operators introduced by Helgason, and mu(m) (p) are the coefficients of the Fourier series expansion of mu(theta, p). (c) 2005 WILEY-VCH Verlag GmbH C Co.
