Relative asymptotics for orthogonal matrix polynomials with unbounded recurrence coefficients
Hossain Oulad Yakhlef · Integral Transforms and Special Functions · 2006
We study the asymptotic behavior of the ratio of two sequences of orthonormal matrix polynomials P n (with unbounded three-term recurrence coefficients) and [Ptilde] n , which are associated, respectively, to a matrix of measures and its perturbation by the addition of a Dirac matrix measure.
