and the Lucas numbers L = [l.sub.n] = ..., -4,3, -1,2,1,3,4, ..., which are named after the French mathematician Edouard Lucas.
By setting x = 1 in these corollaries, we can easily deduce the following interesting identity involving the Fibonacci numbers and the Lucas numbers.
And the many interrelations that continue to be found between Fibonacci numbers, Lucas numbers, the golden section, and geometrical patterns in nature are startling enough to call for periodic international conferences to discuss them.

There are many very interesting and important results related to Fibonacci numbers and Lucas numbers; some of them can be found in Yi and Zhang , Ozeki , Prodinger , Melham , and Wang and Zhang .

For example, they proved that 2 and 3 are the only solutions of K(n) = [n.sup.2]; If a, b > 5, then K(a x b) > K(a) x K(b); If a > 5, then for all positive integer n, K([a.sup.n]) > n x K(a); The Fibonacci numbers and the Lucas numbers do not exist in the sequence {K(n)}; Let C be the continued fraction of the sequence {K(n)}, then C is convergent and 2 < C < 3; K([2.sup.n]-1)+1 is a triangular number; The series [[infinity].summation over (n=1)] 1/K(n) is convergent.
