Algebraic generalizations of discrete groups

the long version

"Building on the achievements of combinatorial group theory, first established as a response to infinite discrete groups used in topological studies by Poincare, this reference/text thoroughly surveys one-relator groups and one-relator products of cyclic groups - extending the algebraic study of Fuchsian groups to the more general context of one-relator products and related group theoretical constructions."--BOOK JACKET. "Algebraic Generalizations of Discrete Groups is an indispensable reference for pure and applied mathematicians, algebraist, and number theorists, and a superb text for graduate students in these disciplines."--BOOK JACKET.
