Hypercentral unit groups and the hyperbolicity of a modular group algebra. (English) Zbl 1142.16300
Summary: We classify groups \(G\) such that the unit group \(\mathcal U_1(\mathbb{Z} G)\) is hypercentral. In the second part, we classify groups \(G\) whose modular group algebra has hyperbolic unit groups \(\mathcal U_1(KG)\).
