Lower bounds of discrete moments of the derivatives of the Riemann zeta-function on the critical line
Journal de théorie des nombres de Bordeaux, Volume 25 (2013) no. 2, p. 285-305

We establish unconditional lower bounds for certain discrete moments of the Riemann zeta-function and its derivatives on the critical line. We use these discrete moments to give unconditional lower bounds for the continuous moments ${I}_{k,l}\left(T\right)={\int }_{0}^{T}{|{\zeta }^{\left(l\right)}\left(\frac{1}{2}+it\right)|}^{2k}dt$, where $l$ is a non-negative integer and $k\ge 1$ a rational number. In particular, these lower bounds are of the expected order of magnitude for ${I}_{k,l}\left(T\right)$.

Nous établissons des bornes inférieures inconditionnelles pour certains moments discrets de la fonction zêta de Riemann et de ses dérivées dans la bande critique. Nous utilisons ces moments discrets pour donner des bornes inférieures inconditionnelles pour les moments continus ${I}_{k,l}\left(T\right)={\int }_{0}^{T}{|{\zeta }^{\left(l\right)}\left(\frac{1}{2}+it\right)|}^{2k}dt$, où $l$ est un entier positif et $k\ge 1$ un nombre rationnel. En particulier, ces bornes inférieures sont de l’ordre de grandeur attendu pour ${I}_{k,l}\left(T\right)$.
