Graph Separators with Applications is devoted to techniques for obtaining upper and lower bounds on the sizes of graph separators - upper bounds being obtained via decomposition algorithms. The book surveys the main approaches to obtaining good graph separations, while the main focus of the book is on techniques for deriving lower bounds on the sizes of graph separators. This asymmetry in focus reflects our perception that the work on upper bounds, or algorithms, for graph separation is much better represented in the standard theory literature than is the work on...

Research in the field of parallel computer architectures and parallel algorithms has been very successful in recent years, and further progress isto be expected. On the other hand, the question of basic principles of the architecture of universal parallel computers and their realizations is still wide open. The answer to this question must be regarded as mostimportant for the further development of parallel computing and especially for user acceptance. The First Heinz Nixdorf Symposium brought together leading experts in the field of parallel computing and its applications to discuss the...

On May 1, 2004, the world of theoretical computer science su?ered a stunning loss: Shimon Even passed away. Few computer scientists have had as long, s- tained, and in?uential a career as Shimon. Shimon Even was born in Tel-Aviv in 1935. He received a B.Sc. in Elect- cal Engineering from the Technion in 1959, an M.A. in Mathematics from the University of Northern Carolina in 1961, and a Ph.D. in Applied Mathematics from Harvard University in 1963. He held positions at the Technion (1964 67 and 1974 2003), Harvard University (1967 69), the Weizmann Institute (1969 74), and the Tel-Aviv...

The abstract branch of theoretical computer science known as Computation Theory typically appears in undergraduate academic curricula in a form that obscures both the mathematical concepts that are central to the various components of the theory and the relevance of the theory to the typical student. This regrettable situation is due largely to the thematic tension among three main competing principles for organizing the material in the course.

This book is motivated by the belief that a deep understanding of, and operational control over, the few "big" mathematical ideas that...
