Factorizations of groups of automorphisms of a finitely generated module over a commutative ring (Q5903817)

Let \({\mathfrak X}\) be the class of groups of automorphisms of a finitely generated unital module over a commutative associative ring with unity. The author states three theorems concerning X-groups which are the product of pairwise permuting subgroups with various properties. For example, if \(G=AB\) with A and B locally nilpotent then G is hyperabelian.
