Ray · Rudra P. Sarkar Received: 19 March 2010 / Accepted: 8 June 2010 / Published online: 2 July 2010 © Springer-Verlag 2010 Abstract We will show that an uniform treatment yields Wiener–Tauberian type results for various Banach algebras and modules consisting of radial sections of some homogenous vector bundles on rank one Riemannian symmetric spaces G/ K of noncompact type. One example of such a vector bundle is the spinor bundle. The algebras and modules we consider are natural generalizations of the commutative Banach algebra of integrable radial functions on G/ K . The first set of them are Beurling algebras with analytic weights, while the second set arises due to Kunze–Stein phenomenon for noncompact semisimple Lie groups.

This theorem which is well known as the Wiener–Tauberian Theo- rem (WTT), was generalized for abelian locally compact groups where the hypothesis is on a Haar integrable function which has nonvanishing Fourier transform on all unitary characters.
