AN EXTERNAL APPROACH TO UNITARY REPRESENTATIONS
, 1993
"... The principal ideas of harmonic analysis on a locally compact group G which is not necessarily compact or commutative were developed in the 1940s and early 1950s. In this theory, the role of the classical fundamental harmonics is played by the irreducible unitary representations of G. The set of all ..."

THE MOMENT MAPPING FOR UNITARY REPRESENTATIONS
- ANNALS OF GLOBAL ANALYSIS AND GEOMETRY VOL. 8, NO. 3 (1990), 299–313
, 1990
"... For any unitary representation of an arbitrary Lie group I construct a moment mapping from the space of smooth vectors of the representation into the dual of the Lie algebra. This moment mapping is equivariant and smooth. For the space of analytic vectors the same construction is possible and leads ..."

Holomorphic extension of unitary representations
"... Let H be a complex Hilbert space and π: G → U(H) a continuous unitary representation of the Lie group G on H. In this note we will discuss the problem of extending π holomorphically to a complex manifold which carries the structure of a complex semigroup and which contains G as its group of units in ..."

Branching Problems of Unitary Representations
- ICM 2002 · VOL. III · 1–3
, 2003
"... The irreducible decomposition of a unitary representation often contains continuous spectrum when restricted to a non-compact subgroup. The author singles out a nice class of branching problems where each irreducible summand occurs discretely with finite multiplicity (admissible restrictions). Basic ..."

ON UNITARY REPRESENTABILITY OF TOPOLOGICAL GROUPS
, 2006
"... Abstract. We prove that the additive group (E ∗ , τk(E)) of an L∞-Banach space E, with the topology τk(E) of uniform convergence on compact subsets of E, is topologically isomorphic to a subgroup of the unitary group of some Hilbert space (is unitarily representable). This is the same as proving tha ..."

Unitary Representations of Lie Groups with . . .
, 1997
"... We consider the following class of unitary representations π of some (real) Lie group G which has a matched pair of symmetries described as follows: (i) Suppose G has a period-2 automorphism τ, and that the Hilbert space H(π) carries a unitary operator J such that Jπ = (π ◦ τ)J (i.e., selfsimilarity ..."

Unitary Representations Of Reductive Lie Groups

, 1987
"... One of the fundamental problems of abstract harmonic analysis is the determination of the irreducible unitary representations of simple Lie groups. After recalling why this problem is of interest, we discuss the present state of knowledge about it. In the language of Kirillov and Kostant, the pr ..."

A Langlands classification for unitary representations
, 1998
"... The Langlands classification theorem describes all admissible representations of a reductive group G in terms of the tempered representations of Levi subgroups of G. I will describe work with Susana Salamanca-Riba that provides (conjecturally) a similar description of the unitary representation ..."
