Algebraic Generalizations of Discrete Groups

Reviews / Votes

"This is a timely and well-written book that brings together many theorems from an active area of combinatorial group theory. It will serve as both an excellent reference for researchers and a highly recommended text for graduate students."
---Bulletin of the London Mathematical Society
"...presents an introduction to combinatorial group theory through the study of one-relator groups and their generalisations.... The book is a useful addition to the literature on combinatorial group theory, and provides an accessible route into the subject for the beginner."
---Mathematical Reviews, 2000
"...the strength of the book is not a systematic introduction to some parts of combinatorial theory, but the wealth of information, the impressive number of results cited and reported on....serve[s] as a source of information and guide to the parts of combinatorial group theory centering around various tractable classes of generalization of one-relator and Fuchsian groups for which some kind of Freiheitssatz can be proved or some cancellation, diagrammatic or representation methods work, and also to learn some basic methods of combinatorial group theory as applied to the proposed classes of groups....interesting and challenging."
