On Rado conditions for nonlinear Diophantine equations

چکیده
Building on previous work of Di Nasso and Luperi Baglini, we provide general necessary conditions for a Diophantine equation to be partition regular. These are inspired by Rado's characterization regular linear homogeneous equations. We conjecture that these also sufficient regularity, at least equations whose corresponding monovariate polynomial is linear. This would natural generalization theorem. verify such hold the $x^{2}-xy+ax+by+cz=0$ $x^{2}-y^{2}+ax+by+cz=0$ $a,b,c\in \mathbb{Z}$ $abc=0$ or $% a+b+c=0$. To deal with equations, establish new results concerning regularity configurations in $\mathbb{Z}$ as $\left\{ x,x+y,xy+x+y\right\} $, building recent result x,x+y,xy\right\} $.

Diophantine approximation and Diophantine equations
The first course is devoted to the basic setup of Diophantine approximation: we start with rational approximation to a single real number. Firstly, positive results tell us that a real number x has “good” rational approximation p/q, where “good” is when one compares |x − p/q| and q. We discuss Dirichlet’s result in 1842 (see [6] Course N◦2 §2.1) and the Markoff–Lagrange spectrum ([6] Course N◦1...

In this paper we study the equation m−n = py,where p is a prime natural number, p≥ 3. Using the above result, we study the equations x + 6pxy + py = z and the equations ck(x 4 + 6pxy + py) + 4pdk(x y + pxy) = z, where the prime number p ∈ {3, 7, 11, 19} and (ck, dk) is a solution of the Pell equation, either of the form c −pd = 1 or of the form c − pd = −1. I. Preliminaries. We recall some nece...
