In mathematics, Padovan polynomials are a generalization of Padovan sequence numbers. These polynomials are defined by:
The first few Padovan polynomials are:
The Padovan numbers are recovered by evaluating the polynomials P<sub>nâÂÂ3</sub>(x) at x = 1.
Evaluating P<sub>nâÂÂ3</sub>(x) at x = 2 gives the nth Fibonacci number plus (âÂÂ1)<sup>n</sup>.
The ordinary generating function for the sequence is
