Harish-Chandra transform

In mathematical representation theory, the Harish-Chandra transform is a linear map from functions on a reductive Lie group to functions on a parabolic subgroup. It was introduced by Template:Harvs.

The Harish-Chandra transform f^P of a function f on the group G is given by

$f^P(m)=a^{-\rho }\underset{N}{\int }f(nm)dn$

where P = MAN is the Langlands decomposition of a parabolic subgroup.
