Krishnapur et al. [15] studied the length of the fluctuations of nodal lengths of random Laplace eigenfunctions on the standard 2-torus. A key step in the paper is a nontrivial bound for the sixth-order correlation of the integer solutions of the equation m=x2+y2. This is a problem about a certain diophantine equation, studied here in depth using a variety of methods.
