Spectral analysis of Jacobi Matrices and asymptotic properties of orthogonal polynomials

We review basic features of the spectral theory of Hermitian Jacobi operators. The analysis is based on asymptotic properties of the related orthogonal polynomials at infinity for fixed spectral parameter. We discuss various examples of bounded and unbounded Jacobi matrices. This talk is meant to give an introduction to the theory of Jacobi matrices and orthogonal polynomials.

Seminar organized in the context of the project PTDC/MAT/121837/2010.
