q-orthogonal polynomials related to the quantum group Uq(so(5))

Alexander Rozenblyum


Orthogonal polynomials in two discrete variables related to finite-dimensional irreducible representations of the quantum algebra $U_q({\bf so}(5))$ are studied. The polynomials we consider here can be treated as two-dimensional $q$-analogs of Krawtchouk polynomials. Some properties of these polynomials are investigated: the difference equation of the Sturm-Liouville type, the weight function, the corresponding eigenvalues including the explicit description of their multiplicities.
