Normally ordered forms of powers of differential operators and their combinatorics

Briand, Emmanuel Lopes, Samuel A. Rosas Celis, Mercedes Helena

We investigate the combinatorics of the general formulas for the powers of the operator h∂k, where h is a central element of a ring and ∂ is a differential operator. This generalizes previous work on the powers of operators h∂. New formulas for the generalized Stirling numbers are obtained.
