Algebraic integers close to the unit circle

Artūras Dubickas

Vol. 9 (2020), No. 4, 361–370
Abstract

We show that for each d 3 there is a monic integer polynomial P of degree d which is irreducible over  and has two complex conjugate roots as close to the unit circle as is allowed by the Liouville-type inequality.

Keywords
irreducible polynomial, roots close to 1, Mahler measure, resultant
