Virtual braid groups, virtual twin groups and crystallographic groups
Let . Let (resp. ) be the virtual braid group (resp. the
pure virtual braid group), and let (resp. ) be the virtual twin
group (resp. the pure virtual twin group). Let be one of the following
quotients: or where
is the commutator subgroup of . In this paper, we show that is a
crystallographic group and we characterize the elements of finite order and the
conjugacy classes of elements in . Furthermore, we realize explicitly some
Bieberbach groups and infinite virtually cyclic groups in . Finally, we
also study other braid-like groups (welded, unrestricted, flat virtual, flat
welded and Gauss virtual braid group) module the respective commutator subgroup
in each case.Comment: In this new version some general results were added in Section
