A Paley–Wiener theorem for some eigenfunction expansions

Abstract

We prove a general version of Paley–Wiener theorem characterising functions with finite Fourier expansions. The result covers Fourier series on compact symmetric spaces, Hermite and special Hermite expansions as particular cases. Gutzmer's formula plays an important role in the formulation and proof of the theorem.

Keywords.: Segal–Bargmann transform; Hermite and Laguerre functions; Heisenberg groups; Symmetric spaces
