The Landau function and the Riemann Hypothesis

Abstract

The Landau function $g(n)$ is the maximal order of an element of the symmetric group of degree $n$; it is also the largest product of powers of primes whose sum is $\le n$. The main result of this article is that the property " For all $n>0$ , $logg(n)<l{i}^{-1}(n))$ " (where $l{i}^{-1}(n)$ denotes the inverse function of the logarithmic integral) is equivalent to the Riemann hypothesis.
