Abstract
Let {Fn}n≥0 be the sequence of Fibonacci numbers defined by F= 0 , F1= 1 and Fn+2= Fn+1+ Fn for all n≥ 0. In this paper, for an integer d≥ 2 which is square-free, we show that there is at most one value of the positive integer x participating in the Pell equation x2- dy2= ± 4 which is a sum of two Fibonacci numbers, with a few exceptions that we completely characterize.
