%0 Journal Article %T p-elementary subgroups of the Cremona group of rank 3 %A Yuri Prokhorov %J Mathematics %D 2009 %I arXiv %X For the subgroups of the Cremona group $\mathrm{Cr}_3(\mathbb C)$ having the form $(\boldsymbol{\mu}_p)^s$, where $p$ is prime, we obtain an upper bound for $s$. Our bound is sharp if $p\ge 17$. %U http://arxiv.org/abs/0909.3302v5
