Polynomial Identities for Generalized Fibonacci Sequences

Source abstract

The Fibonacci, Lucas, and Pell sequences satisfy certain families of ``polynomial'' identities. While a few members of these families are well-known, we are not able to find a general statement of these identities in the mathematical literature. We show that such polynomial identities exist for many generalized Fibonacci sequences, and we classify sequences that have these identities obtained by two distinct approaches. One approach uses the Girard-Waring formula, while the other relies on Binet's formula and linear algebra.
