Written for students taking a second or third year undergraduate course in mathematics or computer science, this book is the ideal companion to a course in enumeration. Enumeration is a branch of combinatorics where the fundamental subject matter is numerous methods of pattern formation and counting. Introduction to Enumeration provides a comprehensive and practical introduction to this subject giving a clear account of fundamental results and a thorough grounding in the use of powerful techniques and tools.Two major themes run in parallel through the book, generating functions and group theory. The former theme takes enumerative sequences and then uses analytic tools to discover how they are made up. Group theory provides a concise introduction to groups and illustrates how the theory can be used to count the number of symmetries a particular object has. These enrich and extend basic group ideas and techniques.The authors present their material through examples that are carefully chosen to establish key results in a natural setting. The aim is to progressively build fundamental theorems and techniques. This development is interspersed with exercises that consolidate ideas and build confidence. Some exercises are linked to particular sections while others range across a complete chapter. Throughout, there is an attempt to present key enumerative ideas in a graphic way, using diagrams to make them immediately accessible. The development assumes some basic group theory, a familiarity with analytic functions and their power series expansion along with some basic linear algebra.

Kentucky's rich archaeological heritage spans thousands of years, and the Commonwealth remains fertile ground for study of the people who inhabited the midcontinent before, during, and after European settlement. This long-awaited volume brings together the most recent research on Kentucky's prehistory and early history, presenting both an accurate descriptive and an authoritative interpretation of Kentucky's past.The book is arranged chronologically—from the Ice Age to modern times, when issues of preservation and conservation have overtaken questions of identification and classification. For each time slice of Kentucky's past, the contributors describe typical communities and settlement patterns, major changes from previous cultural periods, the nature of the economy and subsistence, artifacts, the general health and characteristics of the people, and regional cultural differences.Sites discussed include the Green River shell mounds, the Central Kentucky Adena mounds and enclosures, Eastern Kentucky rockshelters, the important Wickliffe site at the confluence of the Mississippi and Ohio rivers, Fort Ancient culture villages, and the fortified towns of the Mississippian period in Western Kentucky.The authors draw from a wealth of unpublished material and offer the detailed insights and perspectives of specialists who have focused much of their professional careers on the scientific investigation of Kentucky's prehistory. The book's many graphic elements—maps, artifact drawings, photographs, and village plans—combined with a straightforward and readable text, provide a format that will appeal to the general reader as well as to students and specialists in other fields who wish to learn more about Kentucky's archaeology.

Archaeologists and architects draw upon theoretical perspectives from their fields to provide valuable insights into the structure, development, and meaning of prehistoric communities. Architecture is the most visible physical manifestation of human culture. The built environment envelops our lives and projects our distinctive regional and ethnic identities to the world around us. Archaeology and architecture find common theoretical ground in their perspectives of the homes, spaces, and communities that people create for themselves. Although archaeologists and architects may ask different questions and apply different methods, the results are the same—a deeper understanding of what it means to be human. In this volume, prominent archaeologists examine the architectural design spaces of Mississippian towns and mound centers of the eastern United States. The diverse Mississippian societies, which existed between A.D. 900 and 1700, created some of the largest and most complex Native American archaeological sites in the United States. The dominant architectural feature shared by these communities was one or more large plazas, each of which was often flanked by buildings set on platform mounds. The authors describe the major dimensions of an architectural grammar, centered on the design of the plaza and mound complex that was shared by different societies across the Mississippian world. They then explore these shared architectural features as physical representations or metaphors for Mississippian world views and culture.
