Abstract:As a generalization of Wedderburn's classic theorem, it is shown that the multiplicative group of a noncommutative finite dimensional division algebra cannot be finitely generated. Also, the following conjecture is investigated: An infinite non-central normal subgroup of $ GL_n(D) $ cannot be finitely generated.

Keywords:Division ring   normal subgroup   finitely generated.
