Discrete subgroups of semisimple Lie groups, beyond lattices
Fanny Kassel
Discrete subgroups of SL(2,R) are well understood, and classified by the geometry of the corresponding hyperbolic surfaces. Discrete subgroups of higher-rank semisimple Lie groups,…
-convex cocompactness and higher higher Teichmüller spaces
Jonas Beyrer, Fanny Kassel
For any integers and , let be the pseudo-Riemannian hyperbolic space of signature . We prove that if is the fundamental group of a…
Spectral analysis on pseudo-Riemannian locally symmetric spaces
Fanny Kassel, Toshiyuki Kobayashi
We summarize recent results initiating spectral analysis on pseudo-Riemannian locally symmetric spaces , beyond the classical setting where is compact (e.g. th…
Spectral analysis on standard locally homogeneous spaces
Fanny Kassel, Toshiyuki Kobayashi
Let be a reductive homogeneous space with noncompact, endowed with a -invariant pseudo-Riemannian structure. Let be a reductive subgroup of acting properly o…
Invariant differential operators on spherical homogeneous spaces with overgroups
Fanny Kassel, Toshiyuki Kobayashi
We investigate the structure of the ring of -invariant differential operators on a reductive spherical homogeneous space with an overgroup $\widetilde…
Poincaré series for non-Riemannian locally symmetric spaces
Fanny Kassel, Toshiyuki Kobayashi
The discrete spectrum of the Laplacian has been extensively studied on reductive symmetric spaces and on Riemannian locally symmetric spaces. Here we examine it for the first time…
