Matrix-valued orthogonal polynomials related to (SU (2)× SU (2), diag)

E Koelink, M Van Pruijssen… - International Mathematics …, 2012 - ieeexplore.ieee.org
The matrix-valued spherical functions for the pair (K× K, K), K= SU (2), are studied. By
restriction to the subgroup A, the matrix-valued spherical functions are diagonal. For suitable …

We will show that an uniform treatment yields Wiener–Tauberian type results for various
Banach algebras and modules consisting of radial sections of some homogenous vector …

[PDF][PDF] Matrix-valued Berezin kernels

G van Dijk, M Pevzner - Banach Center Publications, 2002 - academia.edu
Introduction. Studying quantization, FA Berezin (see [1]) introduced a family Bλ of G-invariant
kernels on a Hermitian symmetric space G/K. For “large” values of the parameter λ these …

Spectral analysis for radial sections of some homogeneous vector bundles on certain noncompact Riemannian symmetric spaces
