Query: Systems of orthogonal polynomials defined by hypergeometric type
  equations with application to quantum mechanics   A hypergeometric type equation satisfying certain conditions defines either a
finite or an infinite system of orthogonal polynomials. We present in a unified
and explicit way all these systems of orthogonal polynomials, the associated
special functions and the corresponding raising/lowering operators. The
considered equations are directly related to some Schrodinger type equations
(Poschl-Teller, Scarf, Morse, etc), and the defined special functions are
related to the corresponding bound-state eigenfunctions.
