Invariant analysis and contractions of symmetric spaces : part II
Invariant operators on function spaces on homogeneous trees
Inversion de la transformation de Pompéiu dans le disque hyperbolique (Cas de deux disques).
In this paper we extend the result established for the euclidean space in [3] to the hyperbolic disk. This includes the reconstruction of a function defined in a fixed disk B(0,R) from its averages on disks of radii r1, r2 lying in B(0, R).
