Preface
The articles in this volume, honoring the work of Jacques Carmona, show the diversity,
vitality, and importance of the area of noncommutative harmonic analysis.
Several contributions lead to a new perspective on classical questions.
The article of B. Kostant is concerned with the study of the restriction of finite
dimensional representations of a complex semisimple algebra to the subalgebra of
fixed points of an involution. Several applications are given: the structure of M, the
generalization of the Cartan-Helgason theorem, and a noncompact version of the
Borel-Weil Theorem.
1. Kuder and N. Wallach examine Nagata's counterexample to the Hilbert 14th prob
lem, and deduced new results from revisiting his algorithm in a more representation
theorical framework.
The article of S. Miller and W. Schmid gives a proof of a formula of Voronoi which
generalizes the Poisson formula. The summation involves a particular weight coming
from a coefficient of the L-function of a cuspidal automorphic form of GL(3, IR)/
GL(3, Z). Applications are given.
W. Rossmann shows that, in the McKay correspondence, between irreducible char
acters of finite subgroups of SU (2) and extended Coxeter-Dynkin graphs of type ADE,
characters are themselves given by a uniform formula.
Two contributions concern the description of unitary representations of real semisim
pIe Lie groups.
A. Knapp's article is devoted to the unitarity of the analytic continuation of discrete
series in a Borel-de Siebenthal chamber for a number of cases of classical groups.
D. Barbasch studies the spherical unitary dual of groups U (p, q). He gives in par
ticular the complete determination of the spherical unitary dual of the groups U (n, n)
and U(n + 1, n).
Two contributions are related to the orbit method.
In the case of representations of nilpotent Lie groups, A. Hersant examines some
spaces of relative homology with respect to positive polarizations.
M.S. Khalgui and P. Torasso give a proof for the Plancherel formula of real algebraic
groups, deduced from the philosophy of the orbit method.
x Preface
Two contributions concern invariant distributions on reductive Lie groups or Lie
algebras.
A. Bouaziz proves two results on invariant distributions on the Lie algebra of a
reductive Lie group in the Harish-Chandra class. If such a distribution is supported on
the closure of the orbit of a compact set, Harish-Chandra showed that this distribution
is tempered. Bouaziz shows that its Fourier transform is a locally L I-function. He also
shows the equivalence between two notions of invariant-tempered stable distributions.
M. Libine describes his recent argument of localization. This allows for a geometric
proof of the Schmid-Vilonen result relating the two formulas of characters as an inte
gral over a cycle due to Rossmann, and a fixed point formula. Key ideas are given for
the example of SL(2, lR).
P. Delorme proves an analog for p-adic groups of results of J. Franke, who, in his
proof of a conjecture of A. Borel, introduced a filtration on spaces of -automorphic
forms and described the corresponding graded space.
Y. Baldoni-Silva and M. Vergne find explicit formulae for the total residue of certain
rational functions with poles on hyperplanes determined by the roots of a system of
type An.
Two contributions focus on reductive symmetric spaces.
E. van den Ban gives an introduction to his joint work with H. Schlichtkrull on the
Paley-Wiener Theorem and Plancherel formula for reductive symmetric spaces.
P. Harinck and M.N. Panichi introduce, for a complex semisimple simply -connected
Lie group G a duality between G / G]R and a real form of G called a reversed group.
A correspondence between invariant stable distributions is obtained, generalizing the
correspondence obtained by A. Bouaziz when the real form G]R has a compact Cartan
subgroup.
Two contributions are devoted to deformation quantization.
C. Torossian shows, using Kontsevich graphs, how to deform the Campbell-Hauss
dorff formula for symmetric spaces. This allows him to reobtain Rouviere's result in
the solvable case on the convolution of invariant distributions, and to generalize the
result to a special case of symmetric cases.
P. Bieliavsky and M. Pevzner describe an intertwining map between the regular
representation of SL(2, lR) in the space of COO-functions on the Poincare disk with
a subrepresentation of S L(2, lR) in the space of Coo -functions on lR2 possessing the
Weyl-Moyal star-product. They suggest how to extend the result to the case of hermi
tian symmetric spaces of tube-type.
N. Bopp and H. Rubenthaler describe an explicit functional equation for Zeta distri
butions associated to prehomogeneous spaces for a real reductive group G (lR), in the
sense of Mikio Sato or Godement for Mn (lR). Open orbits are symmetric spaces. Zeta
functions are attached to minimal principal series and to distribution vectors invariant
under isotropy groups of this open orbits.
