Discrete Painlevé equations for recurrence coefficients of orthogonal polynomials
The converse statement is also true and is known as the spectral theorem for orthogonal polynomials : if a family of polynomials satisfies a three-term recurrence relation of the form (1.2), with an > 0 and bn ∈ R and initial conditions p0 = 1 and p−1 = 0, then there exists a probability measure μ on the real line such that these polynomials are orthonormal polynomials satisfying (1.1). This gi...

متن کاملRatio Asymptotics for Orthogonal Matrix Polynomials with Unbounded Recurrence Coefficients
In this work is presented a study on matrix biorthogonal polynomials sequences that satisfy a nonsymmetric recurrence relation with unbounded coefficients. The ratio asymptotic for this family of matrix biorthogonal polynomials is derived in quite general assumptions. It is considered some illustrative examples.
متن کاملRelative Asymptotics for Orthogonal Matrix Polynomials with Convergent Recurrence Coefficients
The asymptotic behavior of #n (d;) #n (d:) and Pn (x, d;) P n (x, d:) is studied. Here (#n (.))n are the leading coefficients of the orthonormal matrix polynomials Pn (x, .) with respect to the matrix measures d; and d: which are related by d;(u)= d:(u)+ k=1 Mk$(u&ck), where Mk are positive definite matrices, $ is the Dirac measure and ck lies outside the support of d: for k=1, ..., N. Finally,...
متن کاملStrong asymptotics of the recurrence coefficients of orthogonal polynomials associated to the generalized Jacobi weight
We study asymptotics of the recurrence coefficients of orthogonal polynomials associated to the generalized Jacobi weight, which is a weight function with a finite number of algebraic singularities on [−1, 1]. The recurrence coefficients can be written in terms of the solution of the corresponding Riemann-Hilbert problem for orthogonal polynomials. Using the steepest descent method of Deift and...
