We give a generalization of the identity proved by J.Worpitzky, by expressing each power $x^n$ as a linear combination of the images of $beta_m$ under the powers of the shift operator E. We encode the coefficients of these linear combinations in a 3-dimensional array - the Eulerian octant - and we find recurrences formulae, explicit expressions and generating functions for its entries.

Abstract
We give a generalization of the identity proved by J.Worpitzky, by expressing each power $x^n$ as a linear combination of the images of $beta_m$ under the powers of the shift operator E. We encode the coefficients of these linear combinations in a 3-dimensional array - the Eulerian octant - and we find recurrences formulae, explicit expressions and generating functions for its entries.File in questo prodotto:
