    Uniform boundedness of $ (SL_2(\mathbb{C}))^{n} $ and $ (PSL_2(\mathbb{C}))^{n} $ by Fawaz Aseeri

    Published 2024-11-01
    “…Motivated by previously known results approximating $ \Delta(G) $ for any algebraic group $ G, $ we find the exact values of the conjugacy diameters of the direct product of finitely many copies of $ SL_2(\mathbb{C}) $ and the direct product of finitely many copies of $ PSL_2(\mathbb{C}). $ We also prove that if $ G_1, \dots, G_n $ be quasisimple groups such that $ G_i $ is uniformly bounded for each $ i\in \{1, \dots, n\}, $ then $ G_1\times\dots \times G_n $ is uniformly bounded. …”
