The Nørlund polynomial (note that the spelling Nörlund also appears in various publications) is a name given by Carlitz (1960) and Adelberg (1997) to the
polynomial 
.
These are implemented in the Wolfram Language
as NorlundB[n,
a], and are defined through the exponential
generating function

(1)
|
(Carlitz 1960).
Sums involving 
are given by

(Carlitz 1960, Gould 1960).
The Nørlund polynomials are related to the Stirling numbers by

|
and
 |
(5)
|
(Carlitz 1960).
The Nørlund polynomials are a special case
 |
(6)
|
of the function 
sometimes known as the generalized Bernoulli polynomial, implemented in the Wolfram
Language as NorlundB[n,
a, z]. These polynomials are defined through the exponential
generating function
