*falling factorials*for discrete classical orthogonal polynomials (Charlier, Krawtchouk, Meixner, and Hahn). This Stieltjes function associated with classical orthogonal polynomials of a discrete variable is solution of a non-homogeneous...

*Δ*-Sobolev inner product. Concretely, we consider the case in which both measures appearing in the inner product correspond to the Pascal distribution (the orthogonal polynomials associated to this distribution are known as Meixner...

*dν*be a measure in ℝ

^{ d }obtained from adding a set of mass points to another measure

*dμ*. Orthogonal polynomials in several variables associated with

*dν*can be explicitly expressed in terms of orthogonal polynomials associated with

*dμ*, so are the reproducing kernels associated with these polynomials. The explicit formulas that are obtained are further specialized in the case of Jacobi measure on...
