The Büchi sequences and Hilbert's Tenth Problem
In this short survey paper we state the Büchi conjecture and discuss its relations with the Hilbert Tenth Problem. We give some generalizations of the conjecture, and include some numerical examples.
The circle method and pairs of quadratic forms
We give non-trivial upper bounds for the number of integral solutions, of given size, of a system of two quadratic form equations in five variables.

The diophantine equation
We make more accessible a neglected simple continued fraction based algorithm due to Lagrange, for deciding the solubility of in relatively prime integers , where , gcd is not a perfect square. In the case of solubility, solutions with least positive y, from each equivalence class, are also constructed. Our paper is a generalisation of an earlier paper by the author on the equation . As in that paper, we use a lemma on unimodular matrices that gives a much simpler proof than Lagrange’s for...
