1. Introduction. In his proof of the irrationality of ζ(3), Apéry [1] gave sequences of rational approximations to ζ(2) = π 2 /6 and to ζ(3) yielding the irrationality measures µ(ζ(2)) < 11.85078. .. and µ(ζ(3)) < 13.41782. .. Several improvements on such irrationality measures were subsequently given, and we refer to the introductions of the papers [3] and… (More)

Let α be an algebraic integer of degree d, not 0 or a root of unity, all of whose conjugates αi are confined to a sector | arg z| ≤ θ. In the paper On the absolute Mahler measure of polynomials having all zeros in a sector, G. Rhin and C. Smyth compute the greatest lower bound c(θ) of the absolute Mahler measure ( ∏d i=1 max(1, |αi|)) of α, for θ belonging… (More)

In this work, we show how suitable generalizations of the integer transfinite diameter of some compact sets in C give very good bounds for coefficients of polynomials with small Mahler measure. By this way, we give the list of all monic irreducible primitive polynomials of Z[X] of degree at most 36 with Mahler measure less than 1. 324... and of degree 38… (More)

The house of an algebraic integer of degree d is the largest modulus of its conjugates. For d ≤ 28, we compute the smallest house > 1 of degree d, say m(d). As a consequence we improve Matveev’s theorem on the lower bound of m(d). We show that, in this range, the conjecture of SchinzelZassenhaus is satisfied. The minimal polynomial of any algebraic integer… (More)

We determine the minimal Mahler measure of a primitive, irreducible, noncyclotomic polynomial with integer coefficients and fixed degree D, for each even degree D ≤ 54. We also compute all primitive, irreducible, noncyclotomic polynomials with measure less than 1.3 and degree at most 44.

We find all 15909 algebraic integers whose conjugates all lie in an ellipse with two of them nonreal, while the others lie in the real interval [−1, 2]. This problem has applications to finding certain subgroups of SL(2,C). We use explicit auxiliary functions related to the generalized integer transfinite diameter of compact subsets of C. This gives good… (More)

Let α be an algebraic integer of degree d, not 0 or a root of unity, all of whose conjugates αi lie in a sector | arg z| ≤ θ. In 1995, G. Rhin and C. Smyth computed the greatest lower bound c(θ) of the absolute Mahler measure ( ∏d i=1 max(1, |αi|)) of α, for θ belonging to nine subintervals of [0, 2π/3]. More recently, in 2004, G. Rhin and Q. Wu improved… (More)

We prove that, for any unit in a real number fieldK of degree n+ 1, there exits only a finite number of n-tuples in K which have a purely periodic expansion by the Jacobi-Perron algorithm. This generalizes the case of continued fractions for n = 1. For n = 2 we give an explicit algorithm to compute all these pairs.
