  • Finitary and Artinian-Finitary Groups over the Integers ℤ 
    Wehrfritz, B.A.F. (Український математичний журнал, 2002)
    In a series of papers, we have considered finitary (that is, Noetherian-finitary) and Artinian-finitary groups of automorphisms of arbitrary modules over arbitrary rings. The structural conclusions for these two classes ...
  • On Cohn's embedding of an enveloping algebra into a division ring 
    Wehrfritz, B.A.F. (Український математичний журнал, 1992)
    In 1961 P. М. Cohn proved that the universal enveloping algebra of any Lie algebra over a field-can be embedded into a division ring. (The Lie algebra is not assumed to be finite dimensional.) Cohn's method is less than ...
  • Some soluble groups of finite rank and some related matrix groups 
    Wehrfritz, B.A.F. (Український математичний журнал, 1991)
    Let G be a torsion-free soluble group of finite rank and F ane field. The group algebra FG is an Ore domain; let D denote its division ring of quotients. it Seems likely that D is always locally residually finite-dimensional ...
