Families of Equivariant Differential Operators and Anti-de Sitter Spaces

Pierre Bäcklund
Mathematical Department, Uppsala University, Box 480, 751 06 Uppsala, Sweden

We prove the existence and uniqueness of a sequence of differential intertwining operators for principal series representations, which are realized on boundaries of anti-de Sitter spaces. Algebraically, these operators correspond to homomorphisms of generalized Verma modules. We relate these families to the asymptotics of eigenfunctions on anti-de Sitter spaces.

Keywords: Anti-de Sitter space, spectral geometry, scattering theory, intertwining operators, Verma modules, conformal differential geometry.
