The theory of buildings was introduced by J Tits in order to focus on geometric and combinatorial aspects of simple groups of Lie type. Since then the theory has blossomed into an extremely active field of mathematical research having deep connections with topics as diverse as algebraic groups, arithmetic groups, finite simple groups, and finite geometries, as well as with graph theory and other aspects of combinatorics. This volume is an up-to-date survey of the theory of buildings with special emphasis on its interaction with related geometries. As such it will be an invaluable guide to all those whose research touches on these themes. The articles presented here are by experts in their respective fields and are based on talks given at the 1988 Buildings and Related Geometries conference at Pingree Park, Colorado. Topics covered include the classification and construction of buildings, finite groups associated with building-like geometries, graphs and association schemes.

Although humble in their function, these carefully crafted barns have shaped the lives of Mainers for centuries. Built long before the days of plastic and plywood, the barns have survived for generations, each with a story to tell. In Bridgton, one barn offered comfort to a sixteen-year-old boy when his father was injured. Another New Gloucester barn was so important to one family that its likeness was engraved on their headstones. Some owners said they would rather see their houses burn than their barns, and others have dedicated their lives and livelihoods to restoring and preserving these buildings. From modest English to grand Victorian, Don Perkins examines the structures, origins and evolution of Maine's barns, demonstrating the vital and precious role they play in people's lives.
