Generalizations
Prodinger gives a related, modular-like transformation: letting
gives
where U and B are the ordinary generating functions associated with the series and, respectively.
The rising k-binomial transform is sometimes defined as
The falling k-binomial transform is
- .
Both are homomorphisms of the kernel of the Hankel transform of a series.
In the case where the binomial transform is defined as
Let this be equal to the function
If a new forward difference table is made and the first elements from each row of this table are taken to form a new sequence, then the second binomial transform of the original sequence is,
If the same process is repeated k times, then it follows that,
Its inverse is,
This can be generalized as,
where is the shift operator.
Its inverse is
