The Jacobi operator on $(- 1, 1)$ and its various $m$ -functions

Fritz Gesztesy, Lance L. Littlejohn, Mateusz Piorkowski +1

We offer a detailed treatment of spectral and Weyl-Titchmarsh-Kodaira theory for all self-adjoint Jacobi operator realizations of the differential expression \begin{align*} τ_{α,β}…

Recurrence Coefficients for Orthogonal Polynomials with a Logarithmic Weight Function

Percy Deift, Mateusz Piorkowski

We prove an asymptotic formula for the recurrence coefficients of orthogonal polynomials with orthogonality measure $lo g (\frac{2}{1 - x}) d x$ on $(- 1, 1)$ . The asymp…
