Abstract

We prove a Plancherel formula for a family of affine Ψ-bundles. As an application, we construct Fourier transforms and asymptotic Schwartz spaces for the family. We then prove the corresponding Poisson summation formula under suitable assumptions. The choice of affine Ψ-bundles we consider is motivated by applications to triple product L-functions explored in another paper of the authors and Leslie.
