Diophantine non-integrability of a third order recurrence with the Laurent property [PDF]

open access: yes, 2006
We consider a one-parameter family of third order nonlinear recurrence relations. Each member of this family satisfies the singularity confinement test, has a conserved quantity, and moreover has the Laurent property: all of the iterates are Laurent ...

Heights and quadratic forms: on Cassels' theorem and its generalizations [PDF]

open access: yes, 2012
In this survey paper, we discuss the classical Cassels' theorem on existence of small-height zeros of quadratic forms over Q and its many extensions, to different fields and rings, as well as to more general situations, such as existence of totally ...

A Kolmogorov theorem for nearly-integrable Poisson systems with asymptotically decaying time-dependent perturbation [PDF]

open access: yes, 2014
The aim of this paper is to prove the Kolmogorov theorem of persistence of Diophantine flows for nearly-integrable Poisson systems associated to a real analytic Hamiltonian with aperiodic time dependence, provided that the perturbation is asymptotically ...

On the algebraic structure of rational discrete dynamical systems [PDF]

open access: yes, 2015
We show how singularities shape the evolution of rational discrete dynamical systems. The stabilisation of the form of the iterates suggests a description providing among other things generalised Hirota form, exact evaluation of the algebraic entropy as ...

Laurent Polynomials and Superintegrable Maps [PDF]

open access: yes, 2007
This article is dedicated to the memory of Vadim Kuznetsov, and begins with some of the author's recollections of him. Thereafter, a brief review of Somos sequences is provided, with particular focus being made on the integrable structure of Somos-4 ...

Integral Points for Multi-norm Tori

open access: yes, 2012
We construct a finite subgroup of Brauer-Manin obstruction for detecting the existence of integral points on integral models of principle homogeneous spaces of multi-norm tori. Several explicit examples are provided.Comment: 25 pages.

p-adic Numbers and the Hasse Principle [PDF]

open access: yes, 2014
Hasse’s local-global principle is the idea that one can find an integer solution to anequation by using the Chinese remainder theorem to piece together solutions modulo powers of each different prime number.

Explicit Chabauty-Kim theory for the thrice punctured line in depth two

open access: yes, 2014
Let $X= \mathbb{P}^1 \setminus \{0,1,\infty\}$, and let $S$ denote a finite set of prime numbers. In an article of 2005, Minhyong Kim gave a new proof of Siegel's theorem for $X$: the set $X(\mathbb{Z}[S^{-1}])$ of $S$-integral points of $X$ is finite ...

Elliptic Curves and Hyperdeterminants in Quantum Gravity [PDF]

open access: yes, 2010
Hyperdeterminants are generalizations of determinants from matrices to multi-dimensional hypermatrices. They were discovered in the 19th century by Arthur Cayley but were largely ignored over a period of 100 years before once again being recognised as ...

Weyl's inequality and systems of forms

open access: yes, 2014
By providing a variant of Weyl's inequality for general systems of forms we establish the Hardy-Littlewood asymptotic formula for the density of integer zeros of systems of quadratic or cubics forms under weaker rank conditions than previously known.
