Combinatorial polynomials as moments, Hankel transforms, and exponential Riordan arrays
Journal of integer sequences, Tome 14 (2011) no. 6
In the case of two combinatorial polynomials, we show that they can exhibited as moments of paramaterized families of orthogonal polynomials, and hence derive their Hankel transforms. Exponential Riordan arrays are the main vehicles used for this. Full version: pdf, dvi, ps, latex
