when A is a torsion-free abelian group of rank one. As a consequence he was able to show that a finite rank torsion-free group M satisfies M ( nat M** if and only if M F A I and pM s M precisely when pA s A, where Ž . M*sHom y, A . Using this Warfield obtained a characterization of Z Ž

If A is a fixed abelian group with endomorphism ring E, then for any group G, Ž . Ž . let G\* s Hom G, A and for any E-module M, let M\* s Hom M, A . The E evaluation map : G ª G\*\* is defined in the usual way and G is A-reflexive if G is an isomorphism. This is strongly related to the question of

Semisimple tensor categories with fusion rules of self-duality for finite abelian groups are classified. As an application, we prove that the Tannaka duals of the dihedral and the quaternion groups of order 8 and the eight-dimensional Hopf algebra of Kac and Paljutkin are not isomorphic as abstract

A Hopf algebra is a pair (A, 2) where A is an associative algebra with identity and 2 a homomorphism form A to A A satisfying certain conditions. If we drop the assumption that A has an identity and if we allow 2 to have values in the socalled multiplier algebra M(A A), we get a natural extension of

In the present paper we give a complete characterisation of subgroup separability of HNN-extensions with finitely generated abelian base group. We are also able to characterise subgroup separability for some families of free-by-cyclic groups and thus answer partially a question of Scott (1987, "Comb
