Finite subgroups of $\textrm {GL}_d (\textbf {C})$ or of $\textrm {GL}_d (\textbf {k})$ for $\textbf {k}$ a number field have been studied extensively. For instance, the Burnside–Schur theorem (see [] and []) says that a torsion subgroup of $\textrm {GL}_d … Web11 de mai. de 2009 · Colin Reid. A residually finite (profinite) group is just infinite if every non-trivial (closed) normal subgroup of is of finite index. This paper considers the problem of determining whether a (closed) subgroup of a just infinite group is itself just infinite.
