Using the framework of partitions and rook placements, we study, in particular, the action of the Weyl algebra on the geometric series, obtaining a generalization of the Worpitzky identity and new recursive formulas for a family of polynomials that include the classical Eulerian polynomials.

This is joint work with Pasquale Petrullo, Domenico Senato, and Maria Manuel Torres.
