Abstract

Let k=Q(d3,ζ3)\mathrm{k}=\mathbb{Q}(\sqrt[3]{d},\zeta_3), with dd a cube-free positive integer. Let Ck,3C_{\mathrm{k},3} be the 33-component of the class group of k\mathrm{k}. By the aid of genus theory, arithmetic proprieties of the pure cubic field Q(d3)\mathbb{Q}(\sqrt[3]{d}) and some results on the 33-class group Ck,3C_{\mathrm{k},3}, we are moving towards the determination of all integers dd such that Ck,3Z/9Z×Z/3ZC_{\mathrm{k},3} \simeq \mathbb{Z}/9\mathbb{Z}\times \mathbb{Z}/3\mathbb{Z}.
