In the present paper, the author solves the following Pompeiu type problem: in a compact two point homogeneous space describe the class of functions with zero integral over each ball of prescribed radius, lying in a fixed ball. The author successfully uses a method which he has previously developed for a related problem, namely the analysis of spherically symmetric uniqueness sets for solutions of convolution equations on the Heisenberg group and on symmetric spaces [Vit. V. Volchkov, Dopov. Nats. Akad. Nauk Ukr., Mat. Pryr. Tekh. Nauky 2005, No. 3, 7–11 (2005; Zbl 1088.43003)]. This method is based on the representation of spherical functions as Euclidean Fourier transforms of compactly supported integrable functions and on the reduction of the original equation to a convolution equation on \(R^1\).
