These relations are used to prove interlacing results for the zeros of Al- Salam–Chihara, continuous q-ultraspherical, q-Meixner–Pollaczek and q-Laguerre polynomials of the same or adjacent degree as one of the parameters is shifted by integer values or continuously within a certain range. Numerical examples are given to illustrate situations where the zeros do not interlace.enSpringerInterlacing of zerosMixed recurrence relationsRelation algebrasOrthogonal polynomialsGenerating functionsMixed recurrence relations and interlacing of the zeros of some q-orthogonal polynomials from different sequencesPostprint Article
