Equivalence of two series of spherical representations of a free group

Annali Di Matematica Pura Ed Applicata, 1993
The spherical principal series of a non-commutative free group may be analytically continued to yield a series of uniformly bounded representations, much as the spherical representations π_{(1/2)+ it} of SL(2, R) may be analytically continued in the ...

Discrete mixture representations of spherical distributions

Statistical Papers
We obtain discrete mixture representations for parametric families of probability distributions on Euclidean spheres, such as the von Mises–Fisher, the Watson and the angular Gaussian families.

Supports of irreducible spherical representations of rational Cherednik algebras of finite Coxeter groups [PDF]

Advances in Mathematics, 2012
In this paper we determine the support of the irreducible spherical representation (i.e., the irreducible quotient of the polynomial representation) of the rational Cherednik algebra of a finite Coxeter group for any value of the parameter c.

Spherical representations of the jacobi group

Abhandlungen aus dem Mathematischen Seminar der Universität Hamburg, 1998
Let \(G^J\) be the Jacobi group over a \(p\)-adic field. The author continues the earlier work (with \textit{R. Berndt}) [Elements of the representation theory of the Jacobi group. Progress in Mathematics 163, Birkhäuser, Basel (1998; Zbl 0931.11013)] and determines spherical vectors for admissible \(G^J\)-representations by explicit calculations in ...

Multiscale Representation and Analysis of Spherical Data by Spherical Wavelets

SIAM Journal on Scientific Computing, 1999
Summary: Classic wavelet methods were developed in the Euclidean spaces for multiscale representation and analysis of regularly sampled signals (time series) and images. This paper introduces a method of representing scattered spherical data by multiscale spherical wavelets. The method extends the recent pioneering work of \textit{F. J. Narcowich} and \

Spherical Representations: From EGI to SAI.

1995
One of the fundamental problems in representing a curved surface is how to define an intrinsic, i.e., viewer independent, coordinate system over the surface. More precisely, in order to establish point matching between model and observed feature distributions over curved surfaces, we need to set up a coordinate system that maps a point on a curved ...
