Erdős problem 1060

The conjecture is about the function f(n)f(n) which counts the number of solutions to kσ(k)=nk\sigma(k)=n, where σ(k)\sigma(k) is the sum of divisors of kk. The first bound is that f(n)f(n) grows slower than any power of n(1log⁡log⁡n)n^(\frac{1}{\log\log n}). The second bound is that f(n)f(n) is at most a power of log⁡n\log n.
