New Fibonacci and Lucas primes
Extending previous searches for prime Fibonacci and Lucas numbers, all probable prime Fibonacci numbers Fn have been determined for 6000 < n ≤ 50000 and all probable prime Lucas numbers Ln have been determined for 1000 < n ≤ 50000. A rigorous proof of primality is given for F9311 and for numbers Ln with n = 1097, 1361, 4787, 4793, 5851, 7741, 10691, 14449, the prime L14449 having 3020 digits. P...
متن کاملFibonacci-Lucas densities
Both Fibonacci and Lucas numbers can be described combinatorially in terms of 0− 1 strings without consecutive ones. In the present article we explore the occupation numbers as well as the correlations between various positions in the corresponding configurations.

متن کاملEquations Involving Arithmetic Functions of Fibonacci and Lucas Numbers
For any positive integer k, let (k) and a(k) be the number of positive integers less than or equal to k and relatively prime to k and the sum of divisors ofk, respectively. In [6] we have shown that 0(Fn) > F^n) and that a(Fn) < Fa{ri) and we have also determined all the cases in which the above inequalities become equalities. A more general inequality of this type was proved in [7]. In [8] ...
متن کاملThe Golden-fibonacci Equivalence
We shall refer to A and B as the large and the small Golden Ratios, respectively, and shall in general simply refer to these and their powers collectively as Golden Numbers. Likewise, the ratio between the neighboring Fibonacci Numbers un+i/un will be called the large Fibonacci Ratio. Here, "large" means that the suffices n + 1 > n, without inference to the values of the u s or their ratio. Its...
متن کاملMaximal hypercubes in Fibonacci and Lucas cubes
The Fibonacci cube Γn is the subgraph of the hypercube induced by the binary strings that contain no two consecutive 1’s. The Lucas cube Λn is obtained 5 from Γn by removing vertices that start and end with 1. We characterize maximal induced hypercubes in Γn and Λn and deduce for any p ≤ n the number of maximal p-dimensional hypercubes in these graphs.
