Diophantine Analysis is a very active domain of mathemat- ical research where one finds more conjectures than results. We collect here a number of open questions concerning Diophantine equations (including Pillai's Conjectures), Diophantine approximation (featuring the abc Conjecture) and transcendental number theory (with, for instance, Schanuel's Conjecture). Some questions related to Mahler's measure and Weil absolute logarithmic height are then considered (e.g., Lehmer's Problem). We also…

Diophantus of Alexandria was a greek mathematician, around 200 AD, who studied mathematical problems, mostly geometrical ones, which he reduced to equations in rational integers or rational numbers.

### Diophantine approximation : the twisted, weighted and mixed theories

This PhD thesis consists of five papers dealing with problems in various branches of Diophantine approximation. The results obtained contribute to the theory of twisted, weighted, multiplicative and

This thesis is concerned with the theory of Diophantine approximation from the point of view of measure theory. After the prolegomena which conclude with a number of conjectures set to understand

### On the arithmetic case of Vojta's conjecture with truncated counting functions

. We prove a Diophantine approximation inequality for rational points in varieties of any dimension, in the direction of Vojta’s conjecture with truncated counting functions. Our results also provide

### Introduction to Diophantine Methods

Let us come back to the problem which was considered in § 1.4.1 and solved by Hermite (Proposition 1.20): Given two integers n0 ≥ 0, n1 ≥ 0, find two polynomials A and B with A of degree ≤ n0 and B

### Classical metric Diophantine approximation revisited

• Mathematics
• 2008
The idea of using measure theoretic concepts to investigate the size of number theoretic sets, originating with E. Borel, has been used for nearly a century. It has led to the development of the

### APPROXIMATIONS FONCTIONNELLES DES COURBES DES ESPACES PROJECTIFS

Algebraic approximation to points in projective spaces offers a new and more flexible approach to algebraic independence theory. When working over the field of algebraic numbers, it leads to open

In 1906, Clark defined and studied the set of p-adic Liouville numbers and, in 1985, Schikhof also studied this set in his book Ultrametric Calculus. In this paper, we introduce the set of weak

: In 1906, Maillet proved that given a non-constant rational function f , with rational coeﬃcients, if (cid:2) is a Liouville number, then so is f ð (cid:2) Þ . Motivated by this fact, in 1984,

### Metric Diophantine Approximation : aspects of recent work

• Mathematics
• 2017
In these notes, we begin by recalling aspects of the classical theory of metric Diophantine approximation; such as theorems of Khintchine, Jarnik, Duffin-Schaeffer and Gallagher. We then describe
