Transactions of the American Mathematical Society, Vol. 288, No. 2 (Apr., 1985), pp. 605-623 (19 pages) Let k be a field, and let G be a countable nilpotent group with centre Z. We show that the group ...
This field examines the interplay between algebraic systems—such as groups, rings, fields and modules—and the powerful analytical framework provided by local-global principles. These principles offer ...
