On polynomials of multiple discrete orthogonality on lattices with shift
Abstract:
We introduce new class of polynomials of multiple orthogonality with respect to the product of r classical discrete weights on integer lattices with shifts. We found explicit representations in the form of Rodrigues formulas. The case of r = 2 weights is described in detail.
