15 p, 305.3 KB On groups of finite rank / Wehrfritz, B. A. F. (Queen Mary University of London. School of Mathematical Sciences)
We study the structure of groups of finite (Prufer) rank in a very wide class of groups and also of central extensions of such groups. As a result we are able to improve, often substantially, on a number of known numerical bounds, in particular on bounds for the rank (resp. [...]

12 p, 290.2 KB Groups with no proper contranormal subgroups / Wehrfritz, B. A. F. (Queen Mary University of London. School of Mathematical Sciences)
We consider which groups G are nilpotent if they have a nilpotent normal subgroup N with G/N a restricted soluble group and if G is the only contranormal subgroup of G. This supplements Kurdachenko, Otal, and Subbotin work of 2009, where they consider the corresponding question but with G/N nilpotent and N a restricted soluble normal subgroup.

7 p, 280.7 KB Right Engel elements of stability groups of general series in vector spaces / Wehrfritz, B. A. F. (Queen Mary University of London. School of Mathematical Sciences)
Let V be an arbitrary vector space over some division ring D, L a general series of subspaces of V covering all of V \ {0} and S the full stability subgroup of L in GL(V). We prove that always the set of bounded right Engel elements of S is equal to the w-th term of the upper central series of S and that the set of right Engel elements of S is frequently equal to the hypercentre of S.

15 p, 315.9 KB On the fixed-point set of an automorphism of a group / Wehrfritz, B. A. F.
Let Ø be an automorphism of a group G. Under variousfiniteness or solubility hypotheses, for example under polycyclicity, the commutator subgroup [G; Ø] has finite index in G if thefixed-point set CG(Ø) of Ø in G isfinite, but not conversely, even for polycyclic groups G. [...]
