Summary:
An Olshanski spherical pair (G, K) is the inductive limit of a sequence of Gelfand pairs (G(n), K(n)). A natural question arises: how a spherical function for (G, K) can be obtained as limit of spherical functions for (G(n), K(n)). In this paper we consider a sequence of Gelfand pairs (G(n), K(n)) related to the Heisenberg group.
