Analysis on Non-Riemannian Locally Symmetric Spaces-An
Application of Invariant Theory.
Symposium on
Representation Theory 2015. Izu-Nagaoka, Shizuoka, Japan, 17-20 November
2015.
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.
