Let α, β and γ be algebraic numbers of respective degrees a, b and c over Q such that α + β + γ = 0. We prove that there exist algebraic numbers α1, β1 and γ1 of the same respective degrees a, b and c over Q such that α1β1γ1 = 1. This proves a previously formulated conjecture. We also investigate the problem of describing the set of triplets (a, b, c) ∈ N for which there exist finite field extensions K/k and L/k (of a fixed field k) of degrees a and b, respectively, such that the degree of the…

In this paper, we first prove that given pairwise distinct algebraic numbers $\alpha_1, \ldots, \alpha_n$, the numbers $\alpha_1+t, \ldots, \alpha_n+t$ are multiplicatively independent for all
