Ia-Automorphisms and Permutational Wreath Products
Infinite groups with many permutable subgroups.
Infinite two-generator groups of class two and their non-abelian tensor squares.
Is Whaples' theorem a group theoretical result?
Isometry groups of non standard metric products
We consider isometry groups of a fairly general class of non standard products of metric spaces. We present sufficient conditions under which the isometry group of a non standard product of metric spaces splits as a permutation group into direct or wreath product of isometry groups of some metric spaces.
