Spectral Decomposition And Matrix-Valued Orthogonal Polynomials
Keywords
Matrix-valued orthogonal polynomials; Spectral theory
Abstract
The relation between the spectral decomposition of a self-adjoint operator which is realizable as a higher order recurrence operator and matrix-valued orthogonal polynomials is investigated. A general construction of such operators from scalar-valued orthogonal polynomials is presented. Two examples of matrix-valued orthogonal polynomials with explicit orthogonality relations and three-term recurrence relation are presented, which both can be considered as 2×2-matrix-valued analogues of subfamilies of Askey-Wilson polynomials. © 2013 Elsevier Ltd.
