Orthogonal polynomials with periodically modulated recurrence coefficients in the Jordan block case
Grzegorz Świderski, Bartosz Trojan
We study orthogonal polynomials with periodically modulated recurrence coefficients when lies on the hard edge of the spectrum of the corresponding periodic Jacobi matrix. In p…

About essential spectra of unbounded Jacobi matrices
Grzegorz Świderski, Bartosz Trojan
We study spectral properties of unbounded Jacobi matrices with periodically modulated or blended entries. Our approach is based on uniform asymptotic analysis of generalized eigenv…

Asymptotic behaviour of Christoffel-Darboux kernel via three-term recurrence relation II
Grzegorz Świderski, Bartosz Trojan
We study orthogonal polynomials with periodically modulated Jacobi parameters in the case when lies on the soft edge of the spectrum of the corresponding periodic Jacobi matrix…
