Powers of two as sums of two Fibonacci numbers
arXiv:1409.8514
Abstract
For an integer , let be the Fibonacci sequence which starts with ( terms) and each term afterwards is the sum of the preceding terms. In this paper, we search for powers of 2 which are sums of two Fibonacci numbers. The main tools used in this work are lower bounds for linear forms in logarithms and a version of the Baker--Davenport reduction method in diophantine approximation. This paper continues and extends the previous work of \cite{BL2} and \cite{BL13}.
