The Nørlund polynomial (also spelled Nörlund polynomial) is a name given by Carlitz (1960) and Adelberg (1999) to the polynomial . These are implemented in the Wolfram
Language as NorlundB[n,
a], and are defined through the exponential
generating function

(Carlitz 1960).

The Nørlund polynomials are related to the Stirling numbers by

The Nørlund polynomials are a special case

of the generalized Bernoulli polynomial , defined by the exponential
generating function

For
this gives the ordinary Bernoulli polynomial
(Roman 1984, p. 93). The generalized
Bernoulli polynomial is implemented in the
Wolfram Language as NorlundB[n,
a, x].
