On a Diophantine Equation with Jacobsthal and Fibonacci Numbers

Abstract

In the present paper, we identify all Jacobsthal numbers that may be expressed as a product of three Fibonacci numbers. More precisely, our main result shows that the only solution to the Diophantine equation FkFlFm = Jn for 2 < k < l < m is expressed as (k,l,m,n) = (5,7,8,12). The proof relies on techniques involving linear forms in logarithms.
