An elegant and fruitful way to bring harmonic analysis into the theory of orthogonal polynomials and special functions, or to associate certain Banach algebras with orthogonal polynomials satisfying a specific but frequently satisfied nonnegative lin

In the theory of orthogonal polynomials, as well as in its intersection with harmonic analysis, it is an important problem to decide whether a given orthogonal polynomial sequence $(P_n(x))_{n\in\mathbb{N}_0}$ satisfies nonnegative linearization of p

In contrast to the group case, amenability and many of its various generalizations are rather strong conditions on the \(\ell ^1\)-algebra of a polynomial hypergroup. In this paper, we study weak amenability and investigate the nonexistence of nonzer

Ziellos wandert Privatdetektiv Conrad Orsini durch das nächtliche Wien. Als er auf der Brücke über den Donaukanal in das wirbelnde Wasser des Flusses blickt, werden in ihm Erinnerungen an seinen letzten, Jahre zurückliegenden Fall als Kriminalbea
