Abstract:In this paper, based on the recursive relationship between Fibonacci and Lucas polynomials, the Fibonacci sequence and Lucas sequence of integral sequences and related to the definition were given. The integral sequences and related to Lucas polynomial were studied. The generating function of and were obtained. When, some identities of the integral sequence and about Lucas sequence, Pell-Lucas sequenceswere obtained.
Keywords: Fibonacci polynomial, Lucas polynomial, integral sequence, Lucas sequence, Pell-Lucas sequence
