The asymptotics for the number of real roots of the Bernoulli polynomials

Abstract

A new short clear proof of the asymptotics for the number $c_n$ of real roots of the Bernoulli polynomials $B_n(x)$, as well as for the maximal root $y_n$: $$y_n=\frac{n}{2\pi e}+\frac{\ln (n)}{4\pi e}+O(1)\text{and}{c}_n=\frac{2n}{\pi e}+\frac{\ln (n)}{\pi e}+O(1).$$
