'This book explains how programming languages actually work, with a wealth of examples. It shows convincingly that these languages go hand-in-hand with the simplest kind of logic. I would enjoy teaching from it.' Robin Milner, University of Cambridge 'A useful and thorough introduction to the structural operational semantics of programming languages.' Gordon Plotkin, University of Edinburgh 'This book is an excellent introduction to the theory of structured operational semantics, an ideal choice for a first course on semantics for students in computer science. The book covers the theory all the way from a few simple mathematical preliminaries to advanced examples of its use in describing and reasoning about modern programming language features. The presentation is a result of the author's experience in teaching the material over more than ten years, and it is unique in its pedagogical approach, guiding the reader gently via illustrative examples and exercises, as well as several invitations to the reader to pause and reflect: a moment's thought.' Mogens Nielsen, Aarhus University Each chapter of the book contains various examples and problems, making it very suitable for teaching purposes. There are more than enough bibliographical directions for starting a thorough study of any of the presented topics. The book does not limit itself to structural operational semantics; it provides introductory information on several related topics. All of these aspects make the book a well-rounded presentation on the subject. The book can be successfully used by students, professionals, and researchers as a good introduction to the semantics of programming languages that will help them describe and reason about the behavior of programs. G. Ciobanu, Computing Reviews Transitions and Trees is a detailed, rigorous, and thorough textbook on structural operational semantics on an advanced undergraduate level. The book's strength is the comprehensive coverage of many aspects of structural operational semantics. Transitions and Trees is generally well written and the large number of examples and interspersed exercises help in understanding the material. Stephan Falke for SIGACT News
