A proof of Casselman's comparison theorem for standard minimal parabolic subalgebra

  title={A proof of Casselman's comparison theorem for standard minimal parabolic subalgebra},
  author={Ning Li and Gang Liu and Jun Yu},
Let G be a real linear reductive group and K be a maximal compact subgroup. Let P be a minimal parabolic subgroup of G with complexified Lie algebra p, and n be its nilradical. In this paper we show that: for any admissible finitely generated moderate growth smooth Fréchet representation V of G, the inclusion VK ⊂ V induces isomorphisms Hi(n, VK) ∼= Hi(n, V ) (i ≥ 0), where VK denotes the (g,K) module of K finite vectors in V . This is called Casselman’s comparison theorem ([12]). As a… 


A comparison theorem for Lie algebra homology groups
Let M be a Harish-Chandra module associated to a nite length, admissible representation of real reductive Lie group G0. Suppose thatp is a parabolic subalgebra of the complexied Lie algebra of G0 and
Canonical Extensions of Harish-Chandra Modules to Representations of G
Let G be the group of R-rational points on a reductive, Zariskiconnected, algebraic group defined over R, let K be a maximal compact subgroup, and let g be the corresponding complexified Lie algebra
Page 55, proof of Lemma 3.13. This proof is incorrect as it stands because it involves an interchange of limits that has not been justified. A naive attempt to fix the proof might involve assuming
Quasi-Equivariant D -Modules, Equivariant Derived Category, and Representations of Reductive Lie Groups
In this note, we describe proofs of certain conjectures on functorial, geometric constructions of representations of a reductive Lie group G R . Our methods have applications beyond the conjectures
A Remark on Casselman’s Comparison Theorem
This paper is an outgrowth of our attempt to understand a comparison theorem of Casselman which asserts that Lie algebra homology groups, with respect to certain nilpotent algebras of a
Fréchet completions of moderate growth old and (somewhat) new results
This article has two objectives. The first is to give a guide to the proof of the (so-called) Casselman-Wallach theorem as it appears in Real Reductive Groups II. The emphasis will be on one aspect
Unitary Representations and Complex Analysis
One of the great classical theorems of representation theory is the Borel-Weil Theorem, which realizes any irreducible unitary representation of a compact connected Lie group as the space of
Topological Vector Spaces
Preface In the notion of a topological vector space, there is a very nice interplay between the algebraic structure of a vector space and a topology on the space, basically so that the vector space
Cohomological Properties of the Canonical Globalizations of Harish–Chandra Modules
In this note we draw consequences of theorems of Kashiwara–Schmid, Casselman, and Schneider–Stuhler. Canonical globalizations of Harish–Chandra modules can be considered as coefficient modules for
