Description: |
I will show the construction of an interesting family of polynomial sequences out of a suitable expansion of powers of the monomial (xr Ds), where x stands for multiplication by x and D is the usual derivative operator. Two well-known members of this family are the Eulerian polynomials and the Narayana polynomials. The other members of the family seem to be new in the literature. I will discuss some common properties of these polynomials and, along the way, touch upon Riordan arrays and make further useful remarks. The material presented in this talk is work in progress.
