# Center is marginal of finite type

(Redirected from Center is marginal)
This article gives the statement, and possibly proof, of the fact that for any group, the subgroup obtained by applying a given subgroup-defining function (i.e., center) always satisfies a particular subgroup property (i.e., marginal subgroup of finite type)}
