Abstract

In the paper [14] A. Schinzel and H. Zassenhaus posed the following conjecture: If α ≠ 0 is an algebraic integer of degree n which is not a root of unity, then there exists a constant c > 0 such that

where α = α₁; and α₂, …, α_n are the conjugates of α.
In this paper we give some information concerning this conjecture. In the proofs of the theorems we use some spectral properties of matrices.
