Abstract

We consider a conjecture of Erdős and Rosenfeld and a conjecture of Ruzsa when the number is a perfect square. In particular, we show that every perfect square $n$ can have at most five divisors between $\sqrt{n} - \sqrt[4]{n}\,(\log n)^{1/7}$ and $\sqrt{n} + \sqrt[4]{n}\,(\log n)^{1/7}$.
