A bstract Partial wave decomposition is one of the main tools within the modern S-matrix
studies. We present a method to compute partial waves for 2→ 2 scattering of spinning …

Given a matrix polynomial, matrix bi-orthogonal polynomials with respect to the sesquilinear
form where is a matrix of Borel measures supported in some infinite subset of the real line …

A bstract Conformal blocks are a central analytic tool for higher dimensional conformal field
theory. We employ Harish-Chandra's radial component map to construct universal Casimir …

We analyze domino tilings of the two-periodic Aztec diamond by means of matrix valued
orthogonal polynomials that we obtain from a reformulation of the Aztec diamond as a non …

In a previous paper we have introduced matrix-valued analogues of the Chebyshev
polynomials by studying matrix-valued spherical functions on SU (2)× SU (2). In particular …

A general family of matrix valued Hermite type orthogonal polynomials is introduced as the
matrix orthogonal polynomials with respect to a weight. The matrix polynomials are …

A long standing question in the theory of orthogonal matrix polynomials is the matrix
Bochner problem, the classification of $ N\times N $ weight matrices $ W (x) $ whose …

In this paper we study matrix valued orthogonal polynomials of one variable associated with
a compact connected Gelfand pair (G, K) of rank one, as a generalization of earlier work by …

We introduce matrix-valued weight functions of arbitrary size, which are analogues of the
weight function for the Gegenbauer or ultraspherical polynomials for the parameter ν> 0 ν> …

In this paper, we exhibit explicitly a sequence of 2 * 2 2× 2 matrix valued orthogonal
polynomials with respect to a weight W_ p, n W p, n, for any pair of real numbers p and n …
