Relative asymptotics for polynomials orthogonal with respect to a discrete Sobolev inner product
G. López, Francisco Marcellán, Walter Van Assche
We investigate the asymptotic properties of orthogonal polynomials for a class of inner products including the discrete Sobolev inner products $\langle h,g \rangle = \int hg\, dμ+…

Weak convergence of orthogonal polynomials
Walter Van Assche
The weak convergence of orthogonal polynomials is given under conditions on the asymptotic behaviour of the coefficients in the three-term recurrence relation. The results generali…

Criterion for the resolvent set of nonsymmetric tridiagonal operators
A. I. Aptekarev, Valeri\uı A. Kaliaguine, Walter Van Assche
We study nonsymmetric tridiagonal operators acting in the Hilbert space and describe the spectrum and the resolvent set of such operators in terms of a continued fraction…
