has only finitely many solutions. Roth’s proof is by contradiction. Assuming that (1.1) has infinitely many solutions, Roth constructed an auxiliary polynomial in a large number of variables, k say, of which all low order partial derivatives vanish in a point (x1/y1, . . . , xk/yk) for certain solutions (x1, y1), . . . , (xk, yk) of (1.1), and then showed, using a non-vanishing result now known as Roth’s lemma, that this is not possible. 
Expansions of algebraic numbers
Classical ways to represent a real number are by its continued fraction expansion or by its expansion in some integer base. It is commonly expected that algebraic irrational numbers behave, in many
A generalised Roth’s theorem
0 Introduction 0.1 History The celebrated Roth’s theorem proved in [Rot55] asserts that the approximation exponent of a real algebraic number is 2. An equivalent, but more detailed statement is the
Extensions of the Cugiani-Mahler theorem
In 1955, Roth established that if ξ is an irrational number such that there are a positive real number e and infinitely many rational numbers p/q with q ≥ 1 and |ξ − p/q| < q−2−e , then ξ is
We define the Mahler measure of f(X) = a0(X−ξ1) · · · (X−ξt) ∈ C[X] by M(f) = |a0| ∏t i=1 max(1, |ξi|). A polynomial f ∈ Z[X] is called primitive if its coefficients have gcd 1 and if its leading
On the generalisation of Roth's theorem
We present two possible generalisations of Roth’s approximation theorem on proper adelic curves, assuming some technical conditions on the behavior of the logarithmic absolute values. We illustrate
Mesures de transcendance et aspects quantitatifs de la méthode de Thue–Siegel–Roth–Schmidt
A proof of the transcendence of a real number ξ based on the Thue–Siegel–Roth–Schmidt method involves generally a sequence (αn)n⩾1 of algebraic numbers of bounded degree or a sequence (xn)n⩾1 of
On the quantitative subspace theorem
In this survey, we give an overview of recent improvements to the quantitative subspace theorem, obtained jointly with R. Ferretti, which follow from the work in [9]. Further, we give a new gap

On the Maillet-Baker continued fractions
Abstract We use the Schmidt Subspace Theorem to establish the transcendence of a class of quasi-periodic continued fractions. This improves earlier works of Maillet and of A. Baker. We also improve

Abstract For a polynomial $f(x)\in\mathbb{Q}[x]$ and rational numbers c, u, we put $f_c(x)\coloneqq f(x)+c$ , and consider the Zsigmondy set $\calZ(f_c,u)$ associated to the sequence


Rational approximations to algebraic numbers
It was proved by Roth in a recent paper that if α is any real algebraic number, and if K > 2, then the inequality has only a finite number of solutions in relatively prime integers p, q ( q > 0) The

Abstract Roth's Theorem says that given ρ < 2 and an algebraic number α, all but finitely many rational numbers x/y satisfy |α - (x/y)|< |y|-ρ. We give upper bounds for the number of these
