The fourth Janko group

A. A. Ivanov9780198527596, 0198527594

This unique reference illustrates how different methods of finite group theory including representation theory, cohomology theory, combinatorial group theory and local analysis are combined to construct one of the last of the sporadic finite simple groups – the fourth Janko Group J_4. Aimed at graduates and researchers in group theory, geometry and algebra, Ivanov’s approach is based on analysis of group amalgams and the geometry of the complexes of these amalgams with emphasis on the underlying theory. An indispensable resource, this book will be a unique and essential reference for researchers in the area.
