Zero distributions via orthogonality
Laurent Baratchart, Reinhold Küstner, Вилмос Тотик · Annales de l’institut Fourier · 2005
We develop a new method to prove asymptotic zero distribution for different kinds of orthogonal polynomials. The method directly uses the orthogonality relations. We illustrate the procedure in four cases: classical orthogonality, non-Hermitian orthogonality, orthogonality in rational approximation of Markov functions and its non- Hermitian variant.
