Roman Bessonov: An introduction to universality for orthogonal polynomials

This talk is an introduction to the concept of univerasilty in the theory of orthogonal polynomials. We will discuss basic objects and illustrate the usage of universality with one particular example: the nonlinear Carleson problem for Golinski-Ibragimov weights. Recent advances and the current state of art in universality will be presented in the forthcoming talk by Benjamin Eichinger.
