New explicitly diagonalizable Hankel matrices related to the Stieltjes-Carlitz polynomials
František Štampach, Pavel Šťovíček
Four new examples of explicitly diagonalizable Hankel matrices depending on a parameter are presented. The Hankel matrices are regarded as matrix operators on the Hilbe…

On Hankel matrices commuting with Jacobi matrices from the Askey scheme
František Štampach, Pavel Šťovíček
A complete characterization is provided of Hankel matrices commuting with Jacobi matrices which correspond to hypergeometric orthogonal polynomials from the Askey scheme. It follow…

On infinite Jacobi matrices with a trace class resolvent
Pavel Stovicek
Let be an orthonormal polynomial sequence and denote by the respective sequence of functions of the second kind. Suppose the Hamburger moment pr…
