Construction à la Ibukiyama of symmetry breaking differential operators, I
Jean-Louis Clerc
The construction of symmetry breaking differential operators, using invariant pluri-harmonic polynomials, due to T. Ibukiyama in the context of the Siegel upper half space, is exte…
Spectrum of semisimple locally symmetric spaces and admissibility of spherical representations
Salah Mehdi, Martin Olbrich
We consider compact locally symmetric spaces where is a non-compact semisimple symmetric space and is a discrete subgroup of . We discuss some featur…
Kato's irreducibility criterion for Kac-Moody groups over local fields
Auguste Hébert
In 2014, Braverman, Kazhdan, Patnaik and Bardy-Panse, Gaussent and Rousseau associated Iwahori-Hecke algebras to Kac-Moody groups over non-Archimedean local fields. In a previous p…
Approximation of nilpotent orbits for simple Lie groups
Lucas Fresse, Salah Mehdi
We propose a systematic and topological study of limits of continuous families of adjoint orbits for non-compact simple Lie groups. This limi…
