The theory of polycyclic groups is a branch of infinite group theory which has a rather different flavour from the rest of that subject. This book is a comprehensive account of the present state of this theory. As well as providing a connected and self-contained account of the group-theoretical background, it explains in detail how deep methods of number theory and algebraic group theory have been used to achieve some very recent and rather spectacular advances in the subject. Up to now, most of this material has only been available in scattered research journals, and some of it is new. This book is the only unified account of these developments, and will be of interest to mathematicians doing research in algebra, and to postgraduate students studying that subject.

With a new introduction by the authors, this paperback edition of Jane Austen and the Fiction of Culture takes the complete body of work of a major novelist as the basis for rethinking ethnographic representation and cross-cultural analysis. Authors Handler and Segal have approached Jane Austen's writing as a source for interpreting the cultural ideology of kinship, social rank, courtship, and marriage in Austen's England. Arguing against the conventional reading of Austen as portrayer and upholder of a well-ordered society, they evaluate the rhetorical techniques that make Austen an effective ethnographer of diverse, though intertwined social realities. They show that Austen undercuts any and all claims to "truth universally acknowledged"-that is, to objective, positive knowledge of human affairs. Jane Austen and the Fiction of Culture invites the reader to confront an ethnography of another time and place whose insights have a direct bearing on contemporary concerns in the humanities and human sciences.
