11Langlands classification — In mathematics, the Langlands classification is a classification of irreducible representations of a reductive Lie group G , suggested by Robert Langlands (1973). More precisely, it classifies the irreducible admissible ( g , K ) modules,for g a… …
12Klein geometry — In mathematics, a Klein geometry is a type of geometry motivated by Felix Klein in his influential Erlangen program. More specifically, it is a homogeneous space X together with a transitive action on X by a Lie group G , which acts as the… …
13Zonal spherical function — In mathematics, a zonal spherical function or often just spherical function is a function on a locally compact group G with compact subgroup K (often a maximal compact subgroup) that arises as the matrix coefficient of a K invariant vector in an… …
14Symmetric space — In differential geometry, representation theory and harmonic analysis, a symmetric space is a smooth manifold whose group of symmetries contains an inversion symmetry about every point. There are two ways to make this precise. In Riemannian… …
15Zuckerman functor — This article is about the Zuckerman induction functor, which is not the same as the (Zuckerman) translation functor. In mathematics, a Zuckerman functor is used to construct representations of real reductive Lie groups from representations of… …
16Admissible representation — In mathematics, admissible representations are a well behaved class of representations used in the representation theory of reductive Lie groups over real or p adic fields. They were introduced by Harish Chandra.Real reductive groupsFor real… …

18Tempered representation — In mathematics, a tempered representation of a linear semisimple Lie group is a representation that has a basis whose matrix coefficients lie in the L p space : L 2+ epsilon;( G ) for any epsilon; gt; 0. FormulationThis condition, as just given,… …
19Möbius transformation — Not to be confused with Möbius transform or Möbius function. In geometry, a Möbius transformation of the plane is a rational function of the form of one complex variable z; here the coefficients a, b, c, d are complex numbers satisfying ad − …
20Prehomogeneous vector space — In mathematics, a prehomogeneous vector space (PVS) is a finite dimensional vector space V together with a subgroup G of GL( V ) such that G has an open dense orbit in V . Prehomogeneous vector spaces were introduced by Mikio Sato in 1970 and… …
