A Gutzmer formula for the complexification of a Riemann symmetric space. We consider a complex manifold and a real Lie group of holomorphic automorphisms of . The question we study is, for a holomorphic function on , to evaluate the integral of over a -orbit by using the harmonic analysis of . When is an annulus in the complex plane and the rotation group, it is solved by a classical formula which is sometimes called Gutzmer’s formula. We establish a generalization of...
