The theory of random graphs is a vital part of the education of any researcher entering the fascinating world of combinatorics. However, due to their diverse nature, the geometric and structural aspects of the theory often remain an obscure part of the formative study of young combinatorialists and probabilists. Moreover, the theory itself, even in its most basic forms, is often considered too advanced to be part of undergraduate curricula, and those who are interested usually learn it mostly through self-study, covering a lot of its fundamentals but little of the more recent developments. This book provides a self-contained and concise introduction to recent developments and techniques for classical problems in the theory of random graphs. Moreover, it covers geometric and topological aspects of the theory and introduces the reader to the diversity and depth of the methods that have been devised in this context.

• An introduction to state-of-the-art developments in the theory of random graphs particularly related to topological, geometric and analytic aspects • Written by established researchers this book brings together in a single volume very different aspects of the theory of random graphs • Covers theoretical background which has applications in various scientific disciplines including telecommunications, astronomy, statistical physics, biology, and computer science, as well as much more recent developments such as the study of social and biological networks

### Review

'The chapter on geometric graphs has plenty of exercises … the book will help many novices make their first steps in the field of random graphs.' Miklós Bóna, MAA Reviews (www.maa.org)
