Unitary Representations and Complex Analysis

  title={Unitary Representations and Complex Analysis},
  author={David A. Vogan},
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 holomorphic sections of a complex line bundle on a homogeneous space. These lectures concern two closely related questions: 1. Why should something like the Borel-Weil Theorem be true? 2. Can it usefully be extended to other Lie groups? 
Analytic torsion, dynamical zeta functions, and the Fried conjecture
We prove the equality of the analytic torsion and the value at zero of a Ruelle dynamical zeta function associated with an acyclic unitarily flat vector bundle on a closed locally symmetric reductive
Topological Frobenius reciprocity and invariant Hermitian forms.
In his article "Unitary Representations and Complex Analysis", David Vogan gives a characterization of the continuous invariant Hermitian forms defined on the compactly supported sheaf cohomology
Complex of twistor operators in symplectic spin geometry
For a symplectic manifold admitting a metaplectic structure (a symplectic analogue of the Riemannian spin structure), we construct a sequence consisting of differential operators using a symplectic
Symplectic Dirac Operator and its Higher Spin Analogues
Symplectic Dirac operator is a symplectic counterpart of the classical Dirac operator known from Clifford analysis or Riemannian geometry. We introduce this operator and mention some of its
Cohomological Induction on Generalized G-Modules to Infinite Dimensional Representations
Extensions and globalizations of Harish-Chandra modules are used to obtain a representation theory that includes the cases of non-compact type of irreducible representations studied in the Vogan
The algebraic version of a conjecture by Vogan
In a recent manuscript, D.Vogan conjectures that four canonical globalizations of Harish-Chandra modules commute with certain n-cohomology groups. In this article we focus on the case of a complex
Relation of the spectra of symplectic Rarita-Schwinger and Dirac operators on flat symplectic manifolds
Consider a flat symplectic manifold (M, ω), l ≥ 2, admitting a metaplectic structure. We prove that the symplectic twistor operator maps the eigenvectors of the symplectic Dirac operator, that are
The n-homology groups of a g-module provide a natural and fruitful extension of the concept of highest weight to the representation theory of a noncompact reductive Lie group. In this article we give


Unitary Representations of Reductive Lie Groups.
This book is an expanded version of the Hermann Weyl Lectures given at the Institute for Advanced Study in January 1986. It outlines some of what is now known about irreducible unitary
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

It is shown that every irreducible representation of the group (at least in case it is complex) is infinitesimally equivalent to one constructed in a certain standard way (Theorem 4).

Transcending classical invariant theory
Let Sp2, (R) = Sp2, = Sp be the real symplectic group of rank n. Let Sp denote the two-fold cover of Sp. There is a unitary representation, constructed by Shale [Sh] and Weil [WA], of Sp that is of

We keep to the notation of the preceding note.1 Since mo is reductive, there will be no essential loss of generality from the point of view of irreducible unitary representations of Mo if we assume
