PROTASOV, IHOR; BANACH, TARAS. Ball Structures and Colorings of Graphs and Groups. VNTL Publishers, 2003. ISBN 9667148998, 145 x 215 mm, 148 pp., laminated wrappers.
The ball structures of different kinds arise naturally in the asymptotic topology, geometric group theory and combinatorics. The book is devoted to systematic investigation of purely combinatorical aspects of ball structures of graphs with accent on their applications to partitions of groups and graphs. A lot of new authors results are included. An exposition is supplied with a chain of exercises and open problems. Mathematical Studies: Monograph Series. Volume 11.
