Analysis on Non-Riemannian Locally Symmetric Spaces-An
Application of Invariant Theory.
Seminar. Institut Élie Cartan de Lorraine, Nancy, France, 15

By using invariant thoery for multiplicity-free actions, we
construct joint eigenfunctions on non-Riemannian locally symmetric
spaces modelled on real forms of spherical varieties with overgroups.
