Abstract: In this talk spectral problems for a class of nonlinear dynamical systems will be discussed. It is considered dynamical systems for which associated spectral problem is related with multiple orthogonal polynomials and Hermite–Padé approximants. Some known and new results will be presented.
Joint work with Alexander Aptekarev and Vladimir Lysov.
